MRW I try to rewind a video and it fullscreens instead

Title says it all. Get a notification first thing upon opening the app this morning that I have to update and it won’t let me browse without it. Now anytime I try to grab that pesky slider to rewind something it just fucking full screens instead. End of the world? No. But easily one of the most pea brained no wrinkle havin ass updates to ever update? 10000%
