Thankfully, HBO has now issued a software update that reverts the
playback UI to the original tvOS version. I’ve verified this in
the 50.30.2 update and can confirm everything is back to normal
from skipping ahead to asking Siri ‘What did they say?’ and
everything in between.
You make a mistake, you fix it as fast as you can. Kudos, HBO Max tvOS team.
Someone should send this to the new team behind the MLB app.
