Wifi "connected without Internet" No data plan wanted. I just want to connect to Android Auto.

I have a 2026 GMC 2500 AT4.  After the trial ended for data the truck started having problems connecting to Android Auto.  I have no need for a data plan so therefore I didn't sign up for any OnStar services.  When I crank the truck the My GMC wifi connects but it says connected without Internet and nothing works on .my phone.  It's like the wifi with no internet overrides my cellular data.  The only solution is to pull over, put it in park, and hold microphone button down for 20 seconds to do a soft reset of the infotainment system.

It will usually connect correctly for the rest of the day.  Then the next day it does the same thing over again.  It is beyond frustrating to start your vehicle and have to reset the infotainment system every single day.

I have taken to service department 3 times already.  They have removed negative battery cable 3 different times now.  I have re added my phone wifi and Bluetooth connection several times.  I got a new android phone and it still does the same thing.  I have also made sure the Sharing Vehicle to Phone data is toggled off.  No one seems to have a solution other than sign up for the data plan to make it work.  But it clearly says in the manual that a data plan is not required.  Is it the OnStar Module that is the issue?
