I used to receive push notifications when someone posted on a Discussion that I follow.
This was very useful to me: students post their questions under a week-specific or assignment-specific Discussion, and push notifications allowed me to answer promptly.
I have no longer received push notifications for the past two weeks. When I went to check on my Notifications settings, I discovered this:
I believe push notifications used to be supported, and I did receive them up until a few weeks ago.
Is someone else experiencing the same problem?
