Playbacking FPS content on iOS v15 Beta + Safari fails even if key request succeeds.
I've used Shaka player and other HTML5 players which ends in the same result.
Although, when trying it on AVPlayer, playback succeeds so I guess there is some problem in Safari or somewhere.
Is it a bug and will it be fixed before release?
By the way iOS v14 + Safari + FPS works with no problem.
