App not working

New Contributor

I tried opening the myChevrolet app and it says “the connection between this app and the myChevrolet service is being unexpectedly rerouted by a 3rd Party Process and has been discontinued.” I tried uninstalling and reinstalling the app but it still keeps saying that.

After your upgrade I can no lo get use the app. This is crazy. Ok..update it but do not shut out previous users. So I have a new car and am expected to buy a new phone???. My tablet has Android 12 but you do not allow app to be loaded onto a tablet. Please rectify this.

As of the latest version, the Mobile App no longer supports Android operating systems lower than version 10. We apologize for any inconvenience. With this, if you have any trouble, we are here to help to the best of our abilities. Please feel free to send us an email to with ATTN: OnStar Community/Deeder in the subject headline.
