Should I clear my IPTV app data or only the cache?

Try an app restart and a cache-only clear first if your device offers it. Clearing app data may remove the setup you need to sign in again. Check the restoration method before you use it.

A quick decision

For old thumbnails or a stale guide, restart and try a cache clear. For a repeated crash after an update, make sure you know the account and player installation steps, then consider a reset for that app alone. Test the same action after each change.
