Clearing cache removes temporary files; clearing app data or storage can remove logins, preferences and locally saved lists. The exact controls depend on the operating system. Read the confirmation message carefully so a small troubleshooting step does not unexpectedly become a complete reset.
Choose the smaller action first
Temporary artwork and downloaded guide information can accumulate. If the app is behaving oddly, closing it and clearing its cache may be a reasonable step. It is different from deleting a playlist or resetting the entire device, which changes far more state.
Prepare before a full data reset
Make sure you have the credentials and any supported configuration export. Take note of parental controls and favourite groups without photographing private account fields. A reset can be useful for corrupted settings, but it should be a deliberate choice rather than an automatic response to every error.
Recheck the original symptom
After clearing cache, open the same category or stream that previously failed. Changing several things together makes it impossible to know which action helped. If a fresh login still fails after a complete reset, record that result instead of repeatedly wiping the app.
