Welcome to the forum and sorry to hear you're having trouble casting to your TV. Just to confirm, you're using the built in Google Cast functionality in the TV instead of a separate Chromecast?
Do you see this problem on all content - i.e. both live and catch-up?
Thanks for the quick reply. Can you send me a private message with your BT ID (the username you use to log in to the BT Sport app with) please? I'll take a look at this for you and reply as soon as I have an update.
