My problem I'm sure is shared by others! 

Periodically my tv player's ITV BBC player 4Od etc stop working and also so does my Ability to Cast from my phone etc.

Now the problem is easily fixed by doing a soft reset via the remote but I find this a total pain. 

It's strange because the issue always happens after a good few days sometimes maybe a week. 

I have tried clearing cashe etc which never seems to sort things out. 

I always have to force the TV to restart to correct things..... Anyway any advice would be useful
