iMessage and Facetime not working in 8.3 (iPad 3 Wifi)
After updating to iOS 8.3 iMessage and Facetime is no longer working. iMessage receives messages now and then but is extremely unresponsive, often crashes, and usually only the last message shows. Some of the older ones show at times, but most seems gone. The Messages and Facetime tab in Settings also are extremely unresponsive..takes about half a minute to open. Usually, but not always, I'm told to log on with my Apple ID, which it won't do.
I tried calling my iPad with Facetime. Nothing. Half an hour later it suddenly rang once...
Apps closed, iPad restarted several times to no avail.
