Some delivery resources can be cached, while live playlists and access-controlled media need careful freshness rules. A viewer's refresh is not a command to rebuild the original source. Persistent stale content may require an operator-side correction.
Identify what is stale
An old programme title, outdated guide entry and frozen video are different problems. Note whether time advances and whether the player is actually in replay mode. Avoid calling every repeated image a cache fault.
Use the supported refresh
Refresh the catalogue or guide through the application's documented control. Clearing all storage can remove useful account and favourite data without changing an upstream cache. Start with the narrowest relevant operation.
Report a repeatable mismatch
Give the displayed channel, expected programme and local time zone to support. If another authorised device shows the same stale item, say so. The operator can compare source and cache behaviour more effectively than the viewer can.
