YouTube Tv Glitch

My YouTube app on my flex has had a minor glitch for a while now. When watching YouTube videos on my flex, the bottom of the screen (where the pause, rewind, fast-forward is supposed to be ) is black and those options are no longer there. All that’s there is the channel’s icon, cc options, and the (3 dots) “more” option. I’ve tried turning the tv on and off, refreshing system, restarting flex, and closing and reopening YouTube app, but nothing has worked.
