Push notifications won't work anymore
Hello everyone,
since about two weeks i have noticed that push notifications won't work anymore on my device. Either I don't get any notification at all or it comes late, sometimes even hours after the message was sent to me.
This goes especially for whatsapp and FB messanger.
When i open the apps or log on to wi-fi all missed messages pop up at once, which is quite annoying.
I already tried erverything I could think of to fix the problem.
I turned it off and on, did a hard reset and even restored it from a backup, but nothing helped.
The only thing which helps temporarily is to turn off "search my iPhone", to log of from the Apple-ID under "iTunes & App-Store", reboot the iPhone and log on again.
I hope anyone can help me with this problem, because I have no idea what else I could do.
iPhone 5, iOS 7.1.1
