Notification issues - Some delayed, one user not getting emails
I have notification weirdness that I can't solve. I have two sheets with similar notifications. For one, when the automation is triggered, the notification shows up in a matter of seconds. For the other sheet ,the notification almost always takes one or multiple minutes and some don't seem to show up at all.
Additionally, one user who appears to have email notifications turned on, is not receiving any notifications while others in the organization are. We have gone through the whitelisting process as well.
Any ideas of where to look on these two issues?
