Oh bummer.I had that one and it does NOT work with my 12 Pro Max, I gave it to my coworker. I also had a nice phone/watch charger/stand that didn't work either, so gave it away.
For now until someone figures it out, just using a basic stand and a cable, pretty frustrating.
Mine is a 12 Pro (not the Max) so that means the charging coil is not lined up with the new Max phone ??
Here's my 12 Pro on the Choetech upright charger:
