This app has not been functioning properly for a long time. I keep trying to sign in , it sends me a security code, and then it says unable to connect. I've tried to update and couldn't, then I un-installed the app and reinstalled it, and the same thing happened again. I give up, I would like to control my settings from my phone. Disappointed 😞

Lots of bugs. Profile unlock feature almost never works. Remote actions fail more than succeed. The cycle of this app is: reinstall it, it will appear to barely, slowly work for a day or so, remote start is always unreliable, updating is always unreliable, and after some days the app will lock up requiring reinstall. Support ticket with GM makes you jump through hoops but no resolution in 5 days.

Sometimes the remote features work sometimes they don't. keep getting error that says to turn on vehicle to reconnect. Un-installed app a few times same thing. The shop never loads. Always get error. When app is open the trusted device notification pops up no less than 5 times dinging each time very annoying. Had zero issues with gmc and chevrolet app.
