my GMC app not working after OnStar activated and GMC.com says OnStar no active in my account??

[streetrodder]

just purchased a 11k mile 2023 GMC2500.  Activated OnStar via truck cabin button and shows active in the vehicle information center.  My GMC account shows no OnStar active and MyGMC mobile app keeps asking me to activate OnStar.  Is there a lag time between when you activate and when it shows in the app?  Prior owner had OnStar and i just wanted to transfer to me.  i  deleted and re installed the mobile app without success, just keeps asking me to activate.  Who can  help resolve this please?

Hi. Love the truck but MYGMC is doing the same thing on my phone looking for a solution.

Don't, Mahotey, we'd be happy to help you too. If you haven't yet, please link your GMC account to your OnStar account.

Just got my 2024 youkon, did the onstar call at delivery  and the app still will only let me "get started" by telling me to call onstar to activate everything.  I deleted the app and reinstalled, and nothing.  Quite frustrating

Looks like I'm also having a similar issue. Purchased a 2018 Yukon XL Denali, pressed the button, message said that the service wasn't active so I talked to an advisor and activated my account. She said she was sending a refresh signal to update my unit, and that it would take up to 48 hours to completely activate. It's been about a week and pressing the OnStar button still tells me I don't have an active account, I can't access the my GMC app as far as it talking to the vehicle, or using any of the features BUT I had an additional key made today and got an email alerting me of possible theft, so clearly this thing is communicating, I just can't use any of the features that I'm paying for such as Wi-Fi, remote start, etc. when I called the OnStar advisor they're only advice was to go to the dealer, but when I went to the dealer they just kind of shrugged their shoulders and started talking about replacing multi-thousand dollar control modules when I don't think that's the problem here.

My 2024 GMC Terrain AT4 was working fine with all commands from. The app but now all i get is error notifications unable to start / flash lights / unlock / lock vehicle…. Called OnStar twice but still no resolution and still not working.

I have deleted the app and reinstalled again still the same issue !
