After I got the update when I tried to run Google Maps - either standalone or in the new "desktop" I got a message about when it is safe configure Google Maps on your iPhone. So I opened Google Maps and there was a screen with three options to turn on or off. Worked after that in both modes. Would have been nice if the update told you that you were going to have to do that.
This is also after I updated phone to latest IOS released yesterday but I don't know if that is part of the issue
