Mobile app
It turned out to be 'Autostart' causing the issue for me. I have to have this turned on for it to work. On my version of Android you find it under Settings/Installed Apps/My Citroen.
There are lots of different versions of Android because each manufacturer puts it's own 'skin' over the top of the basic "Android 6/7/etc..). In order to keep the My Citroen app working you have to ensure that it starts automatically and that the phone battery monitoring system does not close it after a while.
I have a sub menu specific to my operating system (Miui9 layered over Android 6) that has the option to disable the 'Miui Battery Saver' on a specific app so as long as I have this disabled and the Autostart enabled, I'm good.
