How can we view NSFW communities from this instance? I tried but was unsuccessful. (I already ticked the box to allow NSFW in settings)

Sure.

For example, I try to see ![email protected]. If I go directly there I won't be able to see anything because I'm not logged in. If I try to search for "![email protected]" in the communities tab in the FMHY instance I get no results. I also tried this from the lemmy.ml instance where I also have another account.

The only solution I see is to create an account on the NSFW instance.

I agree. I'm trying to leave reddit after more than a decade

Thanks, just trying to get used to using Lemmy as a non-tech savvy guy.

It makes sense. Thanks. And I've been able to find almost everything I'm looking for but I still find some issues while searching for newer communities.

For example, I'm looking to subscribe to the blackmetal community from lemmy.ml, I cannot find it under the FMHY instance, but I could find it with my account at the lemmy.ml instance.

Probably I'm doing something wrong, or maybe the servers are saturated.
