What does App cache mean?
An app cache stores temporary or reusable data such as artwork and downloaded metadata. Clearing it is generally narrower than clearing all app data, but the exact behaviour and available controls depend on the operating system and application.
Why it matters
Cache cleanup does not change a server-side password or extend an account. Use it for a relevant local symptom and retest the same action afterwards. Guide data, channel lists and images can also be cached separately, so one refresh may leave another resource unchanged. Avoid treating repeated cache clearing as a substitute for diagnosing an upstream source error.
