Hey good folks, i.e. Rimu & PugJesus@piefed.social / https://piefed.social/u/PugJesus (pardon, not yet sure how to correctly tag here),

I happened to have this same issue last week, and am pleased to see today that the bugfix seems to have worked! Ah, and one other useful thing I discovered was that one can go back and correct a post if one happened to have botched the scheduled time, previously:

I couldn’t find a way to go back to that post directly, but sure enough, I pulled up browser history, went back to the post link, made the edits, and it successfully posted at the corrected, specified time! 😃
