Tesla App won't connect to car

So the last 2 or 3 weeks my Tesla App will not connect to my car unless my phone is on WiFi. If I'm on cellular it will not connect. It just sits there and tries and then tells me Network Error. I have an iPhone 11 running the latest version of iOS. I've tried doing a scroll wheel reboot on the car. I've tried signing out of the Tesla App and back into it. I've also tried deleting the app and reinstalling it. Nothing fixes it. Anyone have any other ideas on how to fix this?

Makes no difference. Still won’t connect if iPhone is on cellular, will if it’s on wifi. Doesn’t have to be my home wifi. Just any WiFi connection.

I'm asking about your CAR. Have you tried removing the wifi from your car so it is only on the car's LTE connection. I have a feeling it's your phone, not the car.
