Probably not affected. It seems user specific. Like I have two accounts one with prime and a business one that doesn't allow prime. I tried with the first episode of Countdown as it is free without prime. I can watch it in chrome browser with my business account but can't with my personal account that has prime. I get the same thing when using streamfab. If you try it outside of streamfab it will have an error when trying to play. I know they changed some endpoints and such so it might end up more widespread soon.

They've changed their end-points alright, it's AWS that's having issues in my case and even the 2nd tier support haven't a clue why it's happening :confused:
