This message has consistently been popping up after about 30 seconds each time I load up BT Sports. I have tried both the online browser (Chrome and Edge) and the TVGO app and they both display the message.
No this is happening on all channels I have tried on TvGo. After around 30 seconds the screen goes off and the message 'Sorry this is not available at this time'. A few people on this forum are having the same issue.
