Bit of a wierd one here
Managed to speak to Land Rover and get the previous owners registration removed from incontrol and registered to my name
On going through the procedure to link to the car i am up and running.
But the app is showing the car as unlocked when it's not
Anyone else had this problem?? 2015 L494 SDV6 3.0 HSE Loire Blue

Yes I've got the same problem. Have had no problems from new (3 + years ago) so has only occurred recently (maybe with recent app update??). It doesn't matter whether I lock with the key or using the door button (both with double lock) it still shows unlocked on the app - even though I know it is definitely locked. I can then 'pretend' to lock it again from the app and it then shows locked.....
I am assuming it is a problem with the app and ignoring the issue for the time being but it is a little irritating.

My did this for a while after the most recent update, not sure if the car updated or a new version came via the app store but worked fine again until I sold the car a couple of weeks ago.
