Me too. Have you fixed it?
Half screen
No, I know there is a way to revert it to the up and down, it just eludes me.... will let you’ll know if I solve it. Like please let me in if you do so before me👍

i suffer with this new version, I have a lot of problems on android tablet with Firefox or Chrome, bad moves, not full screen 😥

I'm having this problem as well. I wonder if when you hit mobile and they offer an app, if the expect you to get it. I thought I already had it. Maybe they expect one version to be for pc and this mobile app to be for phone?? I hope someone else will try it because I don't want to try. But, I did contact support.
i can only see half my screen...on my iPhone
