Ah ok, thx :)

Sorry, I'm just stupid.

So I made a lemmy acccount in this instance lemmy.dbzer0.com. From my very limited research, apparently I can just login to other "federated" instances, but I can't login (infinite time "loading circle" in login page) with the same username and password in both https://lemmy.fmhy.ml/login and https://lemmy.ml/login. Why is that? Any help would be appreciated, sorry if it's obvious because it's not to me
