Car Mirror link apps

I have a problem with Mirror link apps for my car Citroën.
My Fair phone 3 is not detected by my car…

I downloaded Mirror Link at Aurora store.

Would you have any idea why?

Thank you!

Sorry but I have no idea why. But I am intrigued as to what a “Car Mirror link app” is, what it does, and why anybody would need one?

This is a apps to use certain functions on the pilot board in your car.
I need this function on PF3…
