So, this morning, I logged in, and it appears that they really are working on things! I’ve gotten a bunch of replies to archived messages, despite asking students to send new messages because of this problem, and of course, they are replying to old messages. It still shows on the Instructure page as under investigation, but this morning at least, it’s working the way it’s supposed to work.
Incidentally, when I was looking through their support pages, I saw that the 7/20 release is going to incorporate the ability to add a signature block to Canvas messages (aside: Who actually wants this? We want a rich text editor in e-mail, and they are doing a signature block instead? *facepalm*). I’m guessing that, while messing with the code to add the silly signature block, someone messed up the code for replies to archived messages. It should be an easy enough fix, I would think. Anyway, I just wanted to report some positive movement from my side of the keys. Happy Thursday!
