My MY19 50i was on 07/2019 before the update this week. Normally, the exhaust flap stays shut in comfort and stays open in sport once you tap the accelerator.

After the update, regardless of drive mode, the flap stays closed until you're under acceleration. There is noticeably less drone and bass in exhaust at idle and you can no longer flip drive modes and hear the flap click open / closed.

I did plug-in Bimmerlink and was able to open and close the flap manually, so it is responding and functional. Anyone running either 11/2019 or 03/2020 that got a corresponding ISTEP update able to confirm how their flap actuates? Greatly appreciated.
