I am in the same boat as you. it started yesterday. tried iPlayer Sky and YouTube all doing the same. Powered off And on no change. looking for help. it used to last for 30 minutes (exactly) and cut off.
I’ve now tried reset on the box. No difference. checked the version it was up to date. Updated anyway. Still the same. tried a factory reset. Re entered all information and still came up the same. Now Stick downstairs works ok.
