Who I have the same questioned this topic

Purchased a new iphone X replacing my iphone 6 (which worked perfectly). I lose GPS on Waze and Google Maps, when I'm driving. I've  contacted Apple 5 times tried all of the fixes they recommended. Nothing worked. I walked into Apple and they replaced the phone I got at Verizon with a phone from the Apple store. I still can't connect to Waze and Google Maps, I still lose the GPS signal. I need help as I am directionally challenged and I need to drive all over the place for work.
