iOS 15.2 Carplay and phone internet connectivity

Greeting all

I have updated my iPhone to 15.2 and having issues with the Carplay

When my iPhone is connected via carplay I lose internet connectivity on the phone

WiFi says it's connected to my Pioneer unit and when i switch wifi from Pioneer Unit profile to my hotspot or data, carplay disconnects

Previously I would be connected to carplay and have internet connectivity via data plan on my phone

I did notice a new thing on my Pioneer carplay screen, before it was signal bars now it's signal and wifi meter
