Issue is still not solved, even with IOS 14.5 Beta 6. This is my current situation:
An old Nokia Phone or a Apple IPhone 5 with IOS 10 is working fine.
Yeah, I have the same thing happening with my 2012 BMW, but it works fine on my 2018 and 2021 BMW. Also, my daughters Samsung works fine with the 2012 BMW, so its an Apple issue.
