I actually installed it using Obtainium. This is only one example of such popups, but it grayed the post button out at a certain point in the note. I thought it was a length limit or something like on Twitter/X, but it doesn't seem to be from the wording. It wouldn't let me post until I closed the post and repasted my comment again.

That fixed the issue in that instant, but stuff like this happens every time I use the client and it just annoys me enough that I stop using for a while. Rinse and repeat.
