Can't connect the domain I already own

Question:
I Can’t connect the domain I already own.

Product:
Wix domain settings

What are you trying to achieve:
I want to connect the domain I already own (have done it many times earlier).

What have you already tried:
I have entered the domain (my domain.fi), but the only result I get is “.fi domain extension is not available for purchase at Wix.” The issue is that I don’t want to purchase new domain. I just can’t see anymore the optional link: I already own this domain to move on.

I just want to connect the domain via pointing method, but I can’t find the place where to do it anymore.
