MyGMC App will not connect Android phone unable to complete authorization

[T-GMCTerrain]

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.

I have the same issue.  I have tried every troubleshooting step, including removal of my OnStar account and adding it back.  Support has not been able to help. 

I have also tried receiving the code on a different device so that I can make sure I'm staying in the app.  Something in the workflow is failing.

I emailed the above-mentioned address on 10 Aug. which was my third email to OnStar, but nothing is done yet. It seems that they don't have any solution for it. I even installed an older version of the App -as it was fine before- but it did not even let me to try, was forcing me to update! .... Is this problem for those without OnStar subscription?? I tried while in the car and calling OnStar (just the virtual voice, I am not subscribed), but still 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"

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.

I don't know if this is a conclusive or general fix, but it worked for me: I logged in to my my.chevrolet.com account on a browser on my Android phone.  I then signed out and tried the app again, and it successfully accepted the access code.  It may be that the browser interaction allowed the system to establish the phone as a recognized device.  Or, it could have been a random success.
