I suppose it's handy to check and see if the car is locked. Was lying in bed last night and had a sudden thought had I locked the car. Lo and behold I'd forgotten when I went out this morning 😂
The app does let you know if door closed (so from your comment, this does not mean its locked, just closed?), bonnet closed, window closed and lights off with a green tick, and there is a notification that is sent if the door handle has been pulled (presume thats how it works) if someone is going along to see if car been left unlocked.
Does the car not lock itself after a certain period when the key is not in proximity? never tried it, but thought that was how its set to function?
Get the notifications that car is out of area regularly which proves the esim and location mechanisms work.
Might give the VW identification process a go after seen that you have successfully gone through it
