Nreal Adapter doesn't work

It is a very funny story…

I have two pieces of nreal air, there are mine and my friend’s glasses.
I connected my glasses to adapter and it’s works, but when I connect my friend’s glasses - it is doesn’t work. 20sec reset doesn’t help. Does it mean that my glasses linked to adapter?

BUT after updating the second glasses it is working, but in the manual no information about this…

Hi, some glasses come with an old firmware version before coming out from the factory, that is why the glass works after the update.
