Airplay with HBO max simply will not work.

It works fine with other apps and screen mirroring. When screen mirroring everything shows on the TV right up to when I hit play. Then the app on my phone says it’s playing on my TV and in about 3 seconds an error box pops up saying there’s a problem playing the video.

it sure seems like a drm issue as everything else shows up on Airplay to the tv just fine.
