Hello, I am running iOS 11.0.3 with an iPhone 7 plus. I am having issues using WhatsApp, I am in a group with many people within my company and most of the time I do not get any notifications, I have to load up the app to see any new messages that had come through while the phone was in my pocket. The incoming message use to show up on my lock screen and notification center until I clear the notification. But now they do not even show up on my phone at all. Same thing has been happening to mail. Did apple remove push notifications all together?!?!
