Composer not updating elements on screen & viewports don't change

Hey there!

I ran into this issue once before and did a restore to correct the problem. With a site almost done, I can’t do a full restore at this point.

The behavior of the Composer has changed – when I change viewport buttons, rather than switching the view, a black block appears just before some elements.

The big thing is that most elements show an “undo” arrow but there’s nothing to undo.

The site is up but I can’t make changes to existing cloud template pages or post pages.

Thanks so much for your help!
