Hey, same issue here (MBA M1). I thought I was going crazy because it wobbles on the lower right corner on some surfaces and on others it does not. I was running around the house like a lunatic testing every surface I could find. On one corner of the table it is wobbly and on the other it isn't. But it's always the lower right corner of the MBA.. I am going to make an appointment at the Apple Store and have them take a look at it. Any news from the others in this thread? Did you get a replacement unit or could they fix it in the store? If they replaced it: Where you able to take your machine back home until they had a replacement unit? I need my MBA for studying so I can't live to long without it...
