Hello,
Recently I noticed that some notifications started to come 2 or 3 times instead of once (one notification gets sent to student 3 times at the same time).
Not sure which setting I touched… I changed the cron job from every 2min to every 10min, not sure if that can cause the problem... But this is noticeable at least for Assignment feedback, and Certificate.
How can I fix it?
Thanks a lot
