2025 Suburban - Wifi Hotspot doesn't work

I really think it is some kind of issue on OnStar's end, but I am on my third case #. (It worked fine during the trial period.) I have been on and off the phone with OnStar for over two weeks. The WiFi Tech keeps telling me that when they try to activate the WiFi Hotspot on their end it gets rejected by my car. They keep giving me Case numbers and telling me I have to wait for their "Level 2" team to contact me. When if first started I received one email from their "Level 2" team telling me they did some background updates and it should work.  Well it did not change a thing. My Wireless Carplay doesn't work either, so it is apparent that the car is not transmitting a WiFi signal. If it is not resolved by next week, my 6 week old 2025 Chevy Suburban Z71 is going back to the dealer and they can give me a loaner car. I am going to tell them to call me when the issue is fixed and I will come back and pick it up. Keep me updated on if or when they fix your issue.
