To further my question a bit...

I talked to the service director at the dealer yesterday who said that he looked into it and "there is only one 12V receptacle part number BMW has listed". My CA gave me one of the BMW branded 12V adaptors, which does work, but only slow charges at the same speed as the USB port so it's not any help. Below is the BMW adaptor on the left, the Quickcharge 3.0 adaptor that works in my Jeep and an older cable that also works in my Jeep. Neither of the latter 2 work in my BMW. The metal contacts on the sides are in different places although I wouldn't think that would matter since the whole receptacle is metal. All 3 fit plenty secure in the hole. No play at all on any of them so it doesn't appear to be a size issue.

Ideas?
