I experienced the same thing with the first M1 MBAir that I purchased. I took it in for a different issue (because that one had more than one) and I brought it up and demonstrated. They, of course, took their machine(s) and tested it in the same area to make sure, and theirs did not wobble. At first, I scheduled an appointment to take it in so they could ship it off. But then I found out that the repair involved would consist of replacing the top and bottom cases, as well as the display. I asked if since it was so extensive if they couldn't just exchange mine for a different machine. They ultimately did that and, so far, this one is not wobbling, except in places that I already know to be uneven services in some capacity.
