MyGMC App will not connect Android phone unable to complete authorization
I figured it out. For those who are still having issues try to clear your cache from chrome and Microsoft Edge browsers and clear your device cache as well, then try it again. That should work.
SAME On my NEW 2025 CHEVY TRAX I cannot log in to the MyGMC app on my Android phone. I have tried to uninstall and reinstall and that has not fixed the issue. I can enter email and password. I get the email notification with the second security access code, and I enter the code. After that I get a message that says "Unable to complete authorization as there is no interactive call in progress. This can be due to closing the app while authorization was in process"
I did not close the app, I did not leave the app, I did not tough the phone after entering the authorization code and the message above is still happening and it will not connect and it will not complete the authorization.
