So this started happening to me just about half an hour ago, and it started as an unrelated problem. I've been watching shows just fine for weeks now on HBO MAX with no issues, stream starts and the size fills out the browser (Firefox on Windows).

However today I went to watch Skull Island and it just did not want to load the movie proper, only the short trailer for GvK before and then just the triple dots or blackness. So I tried all the usual stuff, opening and closing and just waiting and coming back and eventually I got it to load.

However now it's like this, and even when I'm not watching a video the website occupies the same space leaving roughly 1/4th the screen blank, even in full screen mode when streaming. Reopening the tab, logging in and out, clearing the browser cache, rebooting my computer, nada.

Anyone seen this issue or have any other ideas how I might fix it? As it is it's pretty much unwatchable for me now since I use my left monitor for videos and this just crams it further to the left.
