For some reason the bluetooth audio cuts out after a track or two and will not come back on until restarting bluetooth all together on my 2015 BMW with iDrive (latest idrive firmware). I thought it was the OS at first so I did a network reset first that didn't help. Second I did a full erase of the phone and that didn't work. Then I tried someone elses iPhone 7 and that didn't work either. My friend also said it did not work in his BMW M4 either. So then I went to the dealer and tried it on two other BMWs and it did the same thing there. It was working fine on ios10 just two days ago on my 6S so this is definitely a bug. Unless someone here has any other suggestions.
