My gmc app not working after installing new version

[243ackley]

2021 gmc sierra

I went to use my iPhone app to start my car earlier this week. It said my app was out of date so I updated it.

It still would not work. When I sign in to the new version of the app on my iPhone it says my app is out of date and to update. When I hit update it takes me to the App Store where I can only open.

Then I try to login again and it says service not available.

App version is 6.23.1.

I have deleted and reinstalled The app multiple times and the same thing keeps happening.
