MyGMC app not updating mileage, fuel etc
I’ve got a green Onstar light, checked truck for updates, says it’s up to date, and have rebooted iPhone and deleted/reinstalled app. No change. 2025 Sierra 1500 SLT diesel
ONstar support passed the case to the Engineering team and they resolved within a day. Not sure how but I woke up a couple days later and it was working and has continued working since. I got the email from Engineering that it was resolved about a day later but no details on what exactly was done
