Same here. Tried factory reset Curry’s sending me a new tv as only a week old but not confident any uk players will load on that either
I also have the same issue on a new TCL TV from Currys. My IP address is in the UK, no VPN, all updates applied, network reset didn't help and neither did removing and re-adding the channels. I've also noticed the Freeview Play "What to watch" screen gets stuck on a spinner. I think this and the broken catch up channels must all be related issues.
