Find the largest reversible cleanup
Check free storage in Fire TV's device settings and look through installed apps. Remove an unused app you can reinstall from its official listing. A guide import can need extra space while it processes a new file, so leave some headroom before forcing another refresh.
Understand clear cache and clear data
Clearing a cache removes temporary app files. Clearing data may remove account settings, favourites and imported guide state. If you plan to clear data, confirm that you can sign in and that any export you need is available first. Do the small cleanup and reopen the app before taking the bigger step.
Watch a full refresh complete
Retry the guide update once. Wait for it to finish, restart the player and check that tomorrow's listings are still there. If storage drops again immediately, check guide history settings or ask the player publisher how its database is retained.

Questions readers ask
Will clearing a player’s cache remove my account?
Cache usually contains temporary files. Clearing app data can erase sign-in and settings. Read the confirmation text on the device, and save recovery details before choosing clear data.
