The developers of this app are not intelligent. Ever heard of CLS? It stands for cumulative layout shift. This app is awful because when it opens, the start vehicle button, which is the only reason why I use this app, moves down within a few seconds, after the picture of my car appears. And thanks for removing the send address to vehicle nav 2 years ago—forcing me to use the abysmally slow and awful voice recognition in the car. I'm so thrilled to pay you money each month to remove app features!

1) The app has a survey over the main screen that does not close out. No option to do/not do the survey and I can't see information on the screen behind this survey box. 2) Initially it used biometric log-in. Now I have to manually login and the app stays open. Most times the login has to happen after a few weeks which happens when Im trying to start the car from a diatance. I don't remember the login info. 1) Why is the survey stuck on the screen? 2) Why was the biometric login disabled?

I am thankful for this app. You must have at least a data connect OnStar plan to use this. The app does tend to change on me. For a long time there was a picture of my car, even the correct color. I liked the picture. The picture disappeared and I don't know why. I used to be able to hold down the icon and choose a function, like start or lock, but this disappeared, and I don't know why. Overall good, and useful, but also features come and go. I recommend getting this app and OnStar!
