Google Hangouts says: Connect to iTunes to use Push Notifications
IPhone/iPad Google Hangouts App
Message appears only in Hangouts, I click OK and it goes away. App works ok.
Started a week ago.
At the same time Hangouts no longer rings for incoming calls.
Communications seem to NOW arrive hours later AND there are no longer any alerts.

I tried signing out of the App Store on the device, then a hard re-set/start then signing in again - to no avail.
Tried deleting both accounts from Hangouts and then setting up the accounts again. No help either.
