Convertible windows not dropping on open

Hi - I just picked up a 22 M850C today and the windows don't appear to be dropping at all when I start to open the doors, before I pull the door open. I searched the forum but didn't find any threads on how to reprogram or reset. Does anyone have a link to procedures or have the same issue that they solved? I can see if the dealer is open tomorrow or call BMW Genius but any assist is appreciated. I find the forums are always on point and ahead of the dealership.

Just a thought, if the battery was disconnected at any point, you may need to relearn the window calibration (I think). You can google BMW windows relearn and I think you need to hold up the switch for 60 seconds going through a cycle. At least worth a try.
