Refresh menu cache when non-playable item

[dagwieers]

Describe the feature

Our kids wanted to play the latest Hoodie episode, but we got an error message to check the logs.
By default I always try to disable/enable Widevine to force MPD/HLS, but that didn't work in this case.

After checking the logs below it appeared that this episode (or at least this specific video id) was no longer available, so refreshing the menu was the solution for this problem. The new entry for this video worked immediately and dad was once again the saviour of the day.

So I was wondering, why don't we automatically refresh the cache when an item is no longer available when playing? This would solve such a repeated error immediately, either by removing the item, or replacing it with the newer (updated?) entry.
