What does Guide cache mean?
A guide cache is a local stored copy of programme data that a player can display without downloading the entire guide each time. It improves responsiveness but can become stale if updates fail or the source changes.

A guide-specific refresh is usually more proportionate than deleting an account with working video and carefully organised favourites.
