Choose the smaller action first
A stale thumbnail or a guide that displays old content can justify a cache-only trial. A damaged local configuration that persists after an update and restart may justify a data reset, provided you have the correct player details and are allowed to restore the account. Use the exact menu wording on your model.
Verify the same task after each action
Reopen the app and try the same channel, profile or guide item. Record which action you used and whether the account remained signed in. If only one programme still fails after the cache clears, look at the programme or source rather than repeating a full reset.
