Keep a copy of important study data before trying an operation that overwrites or removes content. ## Templates and field settings :::details What does a template do? A deck has one template, and every card in that deck follows it. The template sets the field names, types, order, sides, and default settings. Each card supplies its own values, and a card can leave some fields empty. See [Templates and presets](https://docs.flashnerd.com/guide/cards/templates.md). ::: :::details Why do template changes matter? A template change applies across the deck, so it can update many cards at once. That same reach is why editing the template can also remove content from cards you did not open individually. ::: :::details What happens if I delete a template field? Deleting a field removes that field and its stored values from every card in the deck. Use it to drop the same unused text or values everywhere in the deck. Changing a field's type can also erase values or formatting. Export a backup before restructuring a populated deck. See [Templates and presets](https://docs.flashnerd.com/guide/cards/templates.md). ::: :::details Can one card use different field settings? By default, every card uses the template's field settings. To change one card, open its editor, tap the gear beside the field, turn off **Use Template Settings**, adjust **General Settings** or the field's **Specific Settings**, then return and save the card. That override stays on that card. Turning **Use Template Settings** back on returns it to the template defaults. Field type and the deck's field structure are still changed in **Deck Detail → Deck Setting → Deck Template**, not in the card override. See [Field settings and card sides](https://docs.flashnerd.com/guide/cards/field-settings.md). ::: :::details Why did a template edit change many cards? Deck template settings apply across the deck. Deleting a field also removes its stored values. Use [templates](https://docs.flashnerd.com/guide/cards/templates.md) to understand deck-wide changes before editing further. ::: ## No cards are available to review :::details Why aren't any cards available to review? 1. Check whether you opened practice from a Home deck or scheduled review from an SRS set. 2. For SRS, confirm the set has linked decks and those decks contain cards. 3. Check due times and **Review Ahead Limit**; a card scheduled for later may not be eligible yet. 4. Check the set's daily limits, weekday-specific limits, and card status. 5. If a session is blocked by credits, use [credits and missions](https://docs.flashnerd.com/guide/accounts/credits-and-missions.md). **Disabled** cards are excluded from SRS review. **Suspended** cards can still be included by the suspended-card quota. Do not use “suspended” as a synonym for “never review.” See [Card status](https://docs.flashnerd.com/guide/srs/card-status.md) and [Daily limits](https://docs.flashnerd.com/reference/srs/daily-limits.md). ::: ## Cards or matching pairs look wrong :::details Why is a card side blank? Check that the card has content and its template assigns a field to **Front**, **Back**, or **Both**. A **Note** field is not a front/back field. ::: :::details Why does Matching have too few pairs? Check the two selected fields and the cards' content. Matching can use only eligible cards with usable values in the chosen fields. See [Matching practice](https://docs.flashnerd.com/guide/practice/matching.md). ::: ## Import problems :::details Why did my CSV header become a card? Enable **Include header** so the first row is treated as labels rather than data. ::: :::details Why did CSV import stop at 999 cards? That is the per-import CSV limit. Split the file and import the remaining rows separately. ::: :::details Why are CSV columns on the wrong sides? Correct **Field Mapping** and verify the deck template's field sides. ::: :::details Why are images or audio missing after import? Check that the original archive contains it, or assign the media separately in CSV import. Missing media can be imported as blank. ::: :::details Why is my media too large? Each image/audio file must fit the 10 MiB limit. Reduce the file size and retry. ::: :::details Why did Anki cards import as notes only? Assign fields to Front, Back, or Both in the deck template before studying or exporting. ::: :::details Why does the Anki archive exceed a processing limit? Simplify or split the source collection; check [Anki limits](https://docs.flashnerd.com/guide/import-export/anki.md). ::: :::details Why is there not enough storage? Free device storage for both preparation and the imported collection, then retry. ::: :::details Why does the destination exceed 20,000 cards? Reduce the reviewed import or use another deck. ::: :::details Why don't Flashnerd fields match? Use a starter template from the destination deck; preserve its field IDs, types, and sides. ::: :::details Why does a card belong to another deck? Turn off **Override existing** for an independent copy, or use cards belonging to the destination. ::: :::details Why are preset references invalid or missing? Export again with the referenced decks, tags, and presets included. ::: ## AI generation and unsaved cards :::details Why does the app say AI usage limit reached? AI generation uses its own weekly allowance. Open the deck's **Generate with AI** screen, then **AI Settings → AI Usage Limit**, and check the UTC reset time. Review credits do not replenish that allowance. Existing drafts can still be reviewed and saved. ::: :::details Why couldn't some cards be generated? A partial result can still be useful. Open it, save the cards you want, and use the send arrow for a clearer follow-up. You do not have to discard the cards that were generated. AI cannot generate images at the moment, however, it can use an image you provide. For **Image Occlusion**, AI can place several masks on that same image. An **Image** field stays empty, and the other fillable fields can still be generated. Add the media after the cards are saved. ::: :::details Why are generated cards missing from the deck? A generated count does not mean the cards are in the deck. A result stays a draft until **Add Cards** succeeds. Reopen **Review cards** in the active conversation and save the cards you want. If you confirmed **Discard this generation?**, the unsaved cards and the conversation are lost. ::: :::details Why can't I select a file? The composer accepts a written prompt, camera or photo images, and TXT, CSV, MP3, WAV, and M4A files. PDF and DOCX are not supported at the moment. See [AI sources and allowance](https://docs.flashnerd.com/guide/ai/limits-and-sources.md). ::: ## Audio, photos, or camera do not work :::details Why don't audio, photos, or camera work? Check Flashnerd's camera, microphone, and photo permissions in your device settings. With limited photo access, make sure the selected image is permitted. For TTS, check the field's language and source text and confirm that the needed voice is installed. See [TTS](https://docs.flashnerd.com/reference/fields/tts.md) and [Audio Recording](https://docs.flashnerd.com/reference/fields/audio.md) for playback and recording controls. ::: ## Sign-in and missing data :::details Why can't I open the app offline? Initial sign-in needs a connection. Reopening offline also needs an existing local profile and a still-valid saved session from a successful online verification. Connect and retry before changing accounts or clearing storage. See [Offline use](https://docs.flashnerd.com/guide/accounts/offline-and-data.md). ::: :::details Why is my collection empty after signing in? Open **Settings → Account Info** and confirm you used the expected linked provider account. Each Flashnerd account has its own local profile. A new device does not automatically download cards from another device; [import your backup](https://docs.flashnerd.com/guide/import-export/backups.md). ::: :::details Why does Apple or Google say it is already in use? That provider identity belongs to another Flashnerd account. Choose a different provider account or sign in to the existing one. Linking does not merge collections. See [Linked accounts](https://docs.flashnerd.com/guide/accounts/sign-in.md). ::: ## Totals or reset times look unexpected :::details Why do totals or reset times look unexpected? Daily missions, check-ins, and ad quotas reset at **00:00 UTC**; weekly missions reset on Monday at **00:00 UTC**. SRS daily limits and study statistics instead use the configured local **Next Day Starts At** boundary. Statistics also distinguish unique cards from repeated attempts, observed retention from estimated recall, and imported history from local events. Check the selected scope and metric definition in [Statistics](https://docs.flashnerd.com/guide/statistics/overview.md). :::
