Software was updated to 1.51.109 yesterday and this morning I found myself in a tug-of-war with the UMC (somewhat amusing, actually). Car was unlocked, handles presented and went to remove UMC. Touched the button and the charging indicator ring turned white and unlocked, for a moment, and then immediately back to green and locked. Tried again and again, same result each time - clicking to white only for a moment then back to green before I could remove the UMC. To an observer, I'm sure the tussle would have looked hilarious. Finally, I just had to be quicker than the car and pulled on the UMC for that split second it remained white. Has anyone else seen this behavior with the charge port and could it have something to do with the latest update of 5.9? Thanks!
