Hi all, I have a 2023 G21. My works phone will connect to the car straight away. My own phone, a Pixel Pro 9 will not. I have tried forgetting the car in my phone settings, the car does not have the phone stored in it's memory. It connects for a split second then immediately disconnects. Interestingly, it won't register as a digital key either. Before I head off to BMW and look foolish, would anyone be able to offer a suggested fix please? Thanks
