Videos on some sites do not play and only give an error message. For example, all game videos from nintendo.com do not play. Only an error message as shown in the image. ""Playback cannot continue. No available working or supported playlists."
Specifically, if Graphics Acceleration is enabled in the Edge settings, the error occurs. If Graphics Acceleration is disabled, the videos will start but that is not a fix as they then only play very slow/choppy/glitchy.
I have tested as far back as Edge 80 and the same videos did not work back then either, and that was FOUR YEARS ago. Also, the same videos DO in fact play with Graphics Acceleration enabled in the Dev and Canary builds, and have worked fine in those builds for a VERY, VERY long time. This issue only effect the Beta and Stable builds, but for some reason whatever is making them work in Dev and Canary has never been pushed to Beta or Stable... for YEARS. They also play without issue on the latest Firefox, Chrome, and Opera browsers.
I have tried resetting all Edge settings, a completely fresh install of Edge Beta and Stable, and also installing them on a fresh installation of Windows. The issue persists.
I have reported this issue via Edge/Help and Feedback/Send Feedback over, and over, and over, and over, and over, and over, and over, and over, and over, and over.... and it is never fixed.
For example, the videos on this page:
