Update to my Jun 16 post....now that I'm on 2.2.10, I am ZERO for FOUR in having auto park recognize any spots (I have a reasonable understanding of the conditions under which it should and shouldn't work, there were plenty of cars, a few spots, no diagonal spots, and I was driving at about the same speed that worked without issue in the past). - it appears to be completely nerfed. Prior to this, with earlier versions, it was picking out spots left, right and center (well...left and right, technically). Since then, big goose egg.
Now I find myself wondering, is it working for anyone in 2.2.10?
