The Gmail app on my Verizon S6 (stock Marshmallow) is again lagging in showing push notifications. I've flushed cache, "uninstalled/reinstalled", everything I can think of short of a FDR. Is anyone else experiencing this? To clarify...there are times when I'll get the push notification of having unread messages. I'll have 2 or 3 messages all of a sudden and then I go look at them, and one message could be from a few hours prior. If I happen to be in Chrome on a PC, I may have a Gmail message waiting in my mailbox and nothing will have alerted my on the phone until I click the message. Doesn't matter if I'm on wifi or carrier's data connection. Anyone else have this happening? I remember this going on a while back too. Seems it's been rearing it's ugly head again.
