Cellular data not working for Siri, Maps
Updated my 6 Plus/ATT to 8.4 this morning. Cellular data not working at least for Siri and Maps. Works fine on wifi. Siri tells me "Sorry, I've lost the Internet connection." Maps says direction not available. Safari and apps accessing internet seem to work ok, just those looking for apple servers (I think!) Haven't had time today to really troubleshoot, although I did the usual, reboot, turn things on and off, location on and off, cellular data, lte on and off, restart some more, reset network, stopped short of restoring, figured wait awhile before going nuclear. Battery seems really hot to me too.
I've seen comments here and there about same/similar problems and AppleInsider was reporting "Cloud based services slow or unresponsive" at around 11:30am ET.
Any ideas or info?
