I had the same problem that night. Now whenever I try to open All4, YouView simply reloads itself. I also tried updating the players in Settings, but it says it can't update Apps & Players - "try again later". I keep doing that - no joy!This has been going on for two days now. Is there a fix for this, please? Thanks!
There is a bug (which I would have thought very simple to fix, but YouView have missed the opportunity to do this on several consecutive releases) where whether it updates Players or not, you get this message.
