Amazon Video Xbox one has a black screen but still has sound

Hi,

That did not make any difference and I tried twice. Still same situation. One video plays fine in perfect quality the following video is all black screen with only audio, but if an Amazon ad plays then that shows fine..

This is EXACTLY how my system is set up. Sound is working perfectly but the video is flashing. Not a constant flash but mainly a black screen then as if the HDR mode keeps resetting, the banner in the upper right corner of the screen signifying hdr has
initialized will get brighter, image that should be showing on screen will appear for a split second and then back to black screen all while the atmos sound never waivers.

I checked the list and have done all they have listed. I have reset the router, factory reset the box, uninstalled and reinstalled the Amazon Prime video.

I have spent 5 hours with amazon support and 2 hours with Xbox support. I have an Xbox One and Xbox One X that have the same problem with Amazon Prime Video.

I can go into Prime Video, select a video, the video will play, I hear the audio but have a black screen.

I have tried the Xbox on two T.V.s. I tried the Amazon Prime Video on the Xbox 360 and it works.

Amazon Prime Video is worked up until 10 days ago. And is the only video app not working correctly.

Amazon instant video has serious frame rate issues, Sound is fine, but the video studders. It worked great until Sunday Afternoon , march 23.

Same problem here in the US for maybe 3 weeks or so. Black screen when I try and play videos. Still have audio and controls show up on the screen. I've tried all the resets / reboots etc... Notice a lot of comments on amazon forums as well but no solutions.
