Can't log into Mycadillac

[dhstron123]

Mycadllac app will not let me log in. It was working 24hrs ago. I have tried uninstalling, reinstalling. No help. I have called OnStar. No help. It tells me to sign in and then nothing. I have seen others with this same problem. I did not see the solution. Please help.
