    🔧 Troubleshooting Common Issues

    Clear Cache button is grayed out

    Cause: Some system apps don't allow cache clearing

    ✅ Solution: Try restarting phone first, or clear data if cache unavailable

    App still has issues after clearing cache

    Cause: Problem is deeper than just cache corruption

    ✅ Solution: Proceed to clear data, but backup important info first

    Lost important data after clearing

    Cause: Cleared data instead of cache, or no backup available

    ✅ Solution: Check app's cloud backup or account sync to restore data
