I noticed that at the list all communities page I see many communities from lemmy.ml, but not all of them.
The two I happened to notice were “covid” and “crypto”. I’m new to Lemmy and don’t know what would cause this. I found this earlier question but the answer implies at least there’s a way for a lemmy.ca user to subscribe to the community in question, and I can’t figure out how to do even that.
I tried going directly to https://lemmy.ca/c/[email protected] but I’m taken to a page that says “Couldn’t find community.”.
All instances? Just lemmy.ca? I see you’re posting from lemmy.ml, so you’d have to describe your situation a little more. Maybe even in a new post relating to the issue, rather than a comment in a post relating to something else entirely.
