I have photographic evidence!
Also a couple people on desktop are saying they can't post, like, the box to type in is literally not there. We're getting them to do cache refreshes since I'm assuming that's the issue. (It's fine on mobile.) Neither are using the extension, but still working on telling if the RTE being off or on is the problem. Turnip tried with both but I know you have to log in and out sometimes for changes to the RTE setting to stick.
