It was recently brought to my attention that agents in one of my projects are no longer receiving emails when a ticket is submitted. This has apparently happened rather recently, and was working perfectly fine before. I have not made any changes to the notifications for their project. The user's also told me they do not change any settings on their side either.
Wanted to know what I can check/change to resolve this issue. Each project I have is setup the same way, and I still get notification emails for the project I am apart of.
