Thanks, Bomb Bloke.

Okay. So it sounds like it's a compatibility bug issue for at least the most essential parts of what I do. And I am in that SOL-boat you describe, given Fandom's non-existent backward compatibility policy. Now to figure out how to break the news to my fellow admins on that wiki, when I can't even find my own message wall. =_=

ETA:  When I checked out the UCP playground a few months ago, the source editor worked. Looks like it loads up to about 80% now, and the progress bar stops. No change in computer or browser. Fortunately there seems to be a workaround for now – using the Undo link on the latest edit in the History takes me to an editor that still works. So go to source editor, copy the source, go back and go to history. Undo. Paste. Make changes. It looks like doing this and abusing the edit comments feature is the only way I can currently communicate with my fellow admins.

I am not pleased, but fortunately, that will most likely not last much longer. It's mostly been fun, but I'm probably going to leave the wiki editing business altogether if this is the UX I can expect.
