For about a week now I've not been getting any notifications.
Checked the app and the system level notification is checked.
Special settings are active for all three of my email accounts. I had the receive settings for the app active as well.
Phone is HTC One M8 on ATT.
UPDATE: I should mention I'm having the same issue on my Hisense tablet. Also, I sent myself an email from one account to another and the notification popped up almost immediately. But other emails....no notifications.
