Just like the previous version (1.6) this new version contains more fixes and underlying work to features coming to the app later this spring. For now, you will not notice any change to the scooter or the app.
P.s.: You can always find out whether your scooter has already received the update and which version you are running with the help of the version box. This appears on your display when you hold down both brake levers for at least five seconds in parking mode.
