I have a 2019 JCW and have had this since I got the 11 Pro Max. The music cut outs, the calls switching between CP and the phone itself and the whole OS slowing down. I have done everything but call Apple. I also have a 2020 Supra ( BMW) with wireless CP...it works perfectly, no issues! My 2018 RS3, perfect and my new 911, perfectly. It is something going on with the Mini OS and CP as none of the other cars have issues. Annoying.
