I thought I would post this just in case anyone else happens to have this issue as well.
One of my teachers that I gave access to set up classes emailed me saying that all of the classes were missing from the JSS. I figured it might have been a weird permission issue with their profile, but when I logged in myself I also did not see any.
I was searching around here and tried Googling as well but didn't see anyone else post specifically about this problem. I figured I would create a couple of dummy classes just to see if a delete all button might appear, but after I created the first class the rest of them reappeared.
Hopefully this is helpful to someone else, or maybe someone will have an explanation for the missing classes.
