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.
All these Onstar advisors keep saying we understand the problem and asking us to send info to onstar support. Why? This is common issue across the board. Why can't you just put the solution here? It is very apparent that mygmc app is having issues with android. Im running android 15. My gmc app was working as of 8/23 and now nothing but white screen, which means I cannot login.
Because they, themselves, don't know what the problem is!! It comes and goes! It all started after they added this damn "two-factor authentication"

It was by accident, sometimes you do those and still won't work! Very tricky!
