This past weekend I upgraded my iPhone 5 from iOS 8.4 to 8.4.1. Ever since my google products will not update or give me lock screen or banner notifications unless I run the app. I use my phone very heavily for work so it's a problem. I use the Hangouts app, Gmail app and Inbox app and none of them work. They work on my iPad and on my wife's phone when I logged in so something is wrong with my phone. Any ideas? It's not the notifications settings or DND or anything. I've played with all that. Help!
