CarPlay stopped working after iOS 18.1.1 update

Hey folks. I did a lot of searching and trying things and finally had success today so I wanted to share. By the way I have a vpn too and in or off that did not help my situation. What worked was this. 1) Delete phone from car and delete car from phone. 2) RENAME phone 3) Reconnect. This solved it for me. Now this is a 2021 Porsche Macan so every car might be different but I’m thinking that the bug has to do with settings embedded in the way our phones used to connect to our cars and somehow that’s married to the profile the phone has which is associated with it’s device name. So when I gave my iPhone a new personalized name it forced a brand new ios18 connection which must have created new connection preferences. I’m speculating here by the way. But whatever the reason, after deleting the car from the phone and the phone from the car and renaming the phone and reconnecting as a new phone…it worked. To rename your phone go to settings>general>about and change the name. Good luck. I hope it works for everyone.
