I’m having the same issues with Bluetooth connectivity. I am unable to track my runs when using the peloton app, and apple play doesn’t stay connected in my car. I’ve checked everything, as well as disconnecting and reconnecting. This didn’t begin until the iOS 17 update, the subsequent updates have not alleviated the problem.
