Start with the checks related to what you were trying to do. Preserve your data while investigating; clearing Android app storage or deleting your account is not a routine repair step.

A card or mode is missing

  • Look in Library → deck → Manage cards, including paused cards.
  • Check deck pause, deck selection, daily limits and precise due-time settings.
  • Check Prioritize new cards when the opposite problem occurs and new additions appear despite the intake limit.
  • Quiz and Second chance need dictionary cards. Word in context and Write it need Recall it. An Anki-only deck uses its templates instead.
  • Practice needs eligible content. Grammar sprint needs a supported gendered language; Aspect pairs and Aspect prefixes are Polish-only.
  • Missing Add decks shortcuts can be restored under Learning → Power → Caught-up / Library page.

A dictionary or course is unavailable

Check the exact language pair, current pack status, network and available device storage. Translation availability does not guarantee a dictionary. Course Creator needs the selected dictionary to be ready and can also require online services or available course allowance.

If a download stalls, read its error and offered retry/cancel action. Reopen the language screen after restoring the connection. Do not delete your Library to repair a resource download.

Audio or reminders do not work

For audio, check media volume, Bluetooth output and a matching Android voice. Imported Anki audio also needs media included in the original package. For reminders, check Android permission, the app’s visible switch, time/threshold, and whether there is actually waiting work. An active holiday suppresses reminders.

An import fails or looks incomplete

Confirm the file is fully downloaded and has a supported format. CSV needs Front and Back columns. Re-export an Anki package with media, scheduling and deck settings if those are required. Read warnings about skipped cards or estimated schedules and compare a few representative cards with the original.

A Remilo JSON file belongs under Settings → Data → Import from a file. It omits media and merges content; changing the extension does not convert the format.

Backup, account or connection problems

Read whether a backup is local or actually uploaded to Drive. Reconnect Drive when prompted. Check that the same intended account is used for ChatGPT or other account-based connections. Resolve an ownership lock through Account. If a restore fails, preserve the source file and try the app’s offered older-backup path where appropriate.

Contact support

Use Settings → Support → Contact us, or contact Remilo. Join us on Telegram opens the community link; Support Remilo opens optional support links. Settings → About shows the app version and product information.

Include the app version, Android phone model, affected language/card type, exact steps and visible error. A screenshot helps if you remove private card contents, account details and codes first. Never send passwords, sign-in tokens, pairing codes or an unencrypted collection export in an ordinary support message.
