Email notifications should be working for most people, just sometimes a random notification will not be sent for some reason. After much code/script research, we are hoping the issue could be tied to one of our servers getting overloaded using too many resources, so we are in the process of migrating to a new web server and should hopefully be done by Monday. We'll check on this again after the new server goes live, to see if it hopefully resolved this issue. For the record, it's effecting our work in the back too, so we are all on the same page. Thank you for your understanding and support, we are truly grateful and working as fast as we can to get this resolved for us all.
