I do NOT like the recent change that puts the vehicle start on the main screen. It is too simple to bump, and if you exit the app before it starts, you might not realize it is running! PLEASE either add a simple confirmation prompt so accidental starts & unlocks are more difficult, or remove the buttons from the main page. Aside from that, the app works well. I have occasionally wished for more than 10 location notifications because they are shared across all vehicles, not 10/ vehicle.

This app used to be great, but since the update, I can barely use it. While I don't love the change to entering your full password every time you sign in, I can deal. It is the fact that I can no longer start my car with it. Just tells me it fails and then locks me out of my car. The locking mechanism just stops reading for about 3 to 4 hours. Can't even use my door locks, nothing reads. I have to uninstall the app to get in. Paying to not be able to use.

Recently, the app gets hung up all the time. I've uninstalled/reinstalled it, forced closed it through, and searched for updates. the start function gets stuck on sending, but doesn't start. i have to send a different command (lock), just so the sending won't display. I'm terrified it'll start eventually at a really inconvenient time. sucks that it happened while it was cold. i miss the warm seats
