I haven't been getting notifications from any messaging apps for a few months. I've checked all the relevant settings (do not disturb etc.). I also get random keyboard issues such as this one. This is my first iPhone. I have no idea why I paid premium prices for a premium phone if they can't even get notifications and typing right
That's a really strange issue you have here. Never heard of anything like this. Could it be possible that some aggressive filtering exists on your network that would disallow your iphone to connect to Apple's push servers ?
