This is all very interesting to me. I weekly create announcements for 30 classes, set the date available, and then copy to the other 29 shells. So I wonder if people are being notified and when.
The reason I ended up on the forums is that I wanted to find a quicker way to copy to multiple classes. Currently, I click three dot menu in announcement>copy to...>copy/paste in the number of the next course>select the correct course>click copy>click close
It is a lot of clicks when you multiply that by 29.
I tried sending to commons, and I could post to multiple courses at one time, but the available date setting disappears, so I can't set those to post at 8am on Monday morning.
Anyway, I will follow this post to see if people are seeing progress! It sounds like the announcements still show up on time, but that maybe people won't be notified.
