Having an issue with the new HBO max channel where eventually the pause function stops working correctly -- The screen goes black, but audio continues playing, and if you hit the "play" button, it advances to the same spot where the audio is (i.e. it continues to play behind the black screen that goes up).
If you exit the app at this point, and then come back into it, HBO max will crash when re-launched. All history of where you were in the program will be lost at this point (It moved me back 3 episodes of GoT the last time this happened, with no recollection I'd watched the next 3).
Mine is doing this too. Along with Prime Video.
I had this sort of happen once. I hit pause and the screen and audio froze, but the time counter continued and when I resumed I was that much further along in the movie. When I tried it again it stopped as expected, and hasn't done it since. It's obviously an issue with the Max channel. While HBO said they had it ready to go all this time, it wasn't really totally ready.
As to the Amazon channel, Amazon has been constantly making changes to their channel (and their app on other devices) for months now, and every new version seems to fix one thing but break another. My wife told me she couldn't watch it at all this morning, but I haven't have time to check it out myself.
