Hi,
I use 3.1.2 and the assignment notifications don't work for me either. I don't get notified when a student submits an assignment, and the students don't get notified when I grade them. Sometimes an email notification would go to the student with a 40-120min delay.
I worked with my hosting provider on the issue, and they cannot figure it out either.
I spend 4 days working on this issue and trying all kinds of setting configurations. Wondering if this is an issue with the newer versions of Moodle...?! Should we try installing an older version?
