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. This is a crucial step for integrating your Connected Services into your app. Be advised, if you are the Owner Proxy or Driver on the account, you must consult with the Owner to authorize this change. If you are the OnStar account Owner, please follow the steps below to link your accounts.

1. Log into your GMC Account via GMC.com or experience.GM.com
2. Once logged in, click on "Plans & Services” from the navigation bar
3. Enter either your OnStar account number or your username (email address associated to your OnStar account)
4. Choose your method of verification (email or text message)
5. Select "Send code"
6. Check either your email address or phone to locate the verification code
7. Once found, enter the verification code into the GMC Account Website
8. Click "Link account" to finish.

Once you have successfully linked your accounts, please log out and then back into your app with your GMC Account credentials. Should you find that these options are not visible to you on the GMC Account site, it's likely that you've already linked your accounts. If these steps do not resolve your concern, you can connect with us at socialmedia@gm.com. Please be sure that you have your subject line as ‘ATTN: OnStar Community/Mahotey’ so we can reference back to this post.

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
