Hey @qwaverob, thanks for the report, and for the side-by-side test with the new bot. That helped narrow it down quickly.
You’re right that this is tied to the account merge. Your existing bots and their history were carried over, but the final step of the merge didn’t finish re-linking them to your merged sign-in. Messages to them are accepted but never start, which is why bots created after the merge work and the older ones sit on “Working on it…”. Scheduled routines on those older bots are affected the same way.
I’ve flagged this to the team. From what we can see, your bots, their conversations and their computers are all still there, so please don’t reset, delete or recreate them in the meantime. That won’t help here.
If something can’t wait, a new bot will work in the meantime, but there’s no need to move anything over. I’ll follow up here as when there’s an update!
