I am having problems with my Sky Sports app on my iPad. Everything has been fine for months, but now when I try to play a channel I get a message saying "Could not play channel. Your subscription doesn't allow you to watch this channel. you can upgrade etc...". I have a full Virgin Media bundle with Sky Sports & BT Sports. When I try the same thing on my iPhone it works fine. Both devices are on the latest version IOS14. I have tried deleting the Sky Sports app from my iPad and reinstalling it with no success. Any suggestions?
