Just to add, I noticed a worrying statement in the vehicle handbook which stated that if you use California on Tour App to open/close the roof then the control panel will not be able top control the roof.
I imagine this is just a translation issue and means that if you are actively using the app to move the roof then the control panel will not work, but still it worried me enough to just give up.
These vehicles are clearly internet connected to enable the Volkswagan App to work, why would the COT App not allow some functions to work while away from the van. Fridge, Lights etc. all fairly harmless. I understand why it might not be desirable for the roof control to be fully remote.
Finally, I find the COT App connection to be non existent outside the van, so what is the point of being able to keep an eye on your lowering roof, but not giving the wifi the range to actually make this a reality.
