I've run into this several times now since September with this car while connected to CarPlay during a phone call, where in the middle of the call - my microphone gets lost and the other party no longer hears me. Each time it happens, I've had to just hang up and call back - and it is has happened often enough to be very inconvenient. I also have a 2021 Audi S4 that also connects with wireless CarPlay, and the same phone in that vehicle has never done that, so I know it's not my phone or my version of iOS. Has anyone else run into this?
