Already covered elsewhere but try rebooting the iDrive (hold volume button in for 20s until screen goes blank) and also do an update of Apps and Services. Started working again for me but had to re-enable it a couple of times in the app.

I recommend the other order: update first, then reboot if needed. Note on reboots:

1. Press and hold the Vol knob until the console screen turns black and reboots. This is a basic reset.
2. Press and hold the Vol knob until the console screen turns black and reboots a total of 3 times. This is a harder reset.
3. Get into the car and press the Start button 3 times (don't press the brake) then press and hold the Vol knob for 3 reboots.

Start with the first. That is likely to fix this problem. If it doesn't, try the second. I'm not sure if you'll need the third, since that's usually for multiple issues according to @niam.
