Hi, I have the same issue with the 4K stick. Does anyone have any ideas?
PS. This is only an issue with the BT Sport channels - Eurosport etc. play fine.
Replying to my own post; having done some searches this would appear to be an incompatibility with the BT TV app, the posts I found are dated mid-late November (on this very forum).
Is this a known issue and is it being addressed is my question?
