I wish it were that simple, but I have no charge with or without a case. iPhone 12 mini with a 2021 MY VIN 705XX. However.... Today, with the mag safe case on, I slowly moved it 1/2 an inch at time, moving it around, replacing it on the pad, even tried upside-down. With about 20 tries, it did engage and charge twice. Both times it was right where you'd expect it should be if you placed the phone in the middle of the left side, with the case resting on that bottom lip. And once it was engaged, I was able to slide it around about 1/2 an inch in any direction and it kept charging. But once I picked it up and put it back down again, no charge. Until maybe 8 more tries later, it mysteriously engaged again. Not sure how to make sense of that. Maybe someone with more tech knowledge?
My car is currently downloading the new software update, I think 2020.48? I can dream that maybe it will fix this.
