I seem to be in the minority. I like the 'inControl', I use it and find it informative.
Never had a problem with it in the year I've had it.
Key feature for me is the ability to check if I've locked the car. saves lots of leg work.

That is 'InControl Remote'. I haven't had any problems with it apart from it being very slow in contacting the car. It is indeed very useful.

'In Control Apps' is a different feature and that's what many think is useless. Current: Volvo XC90 T8 Inscription Pro PHEV with some optionals on top
