I found an active thread in a sub on another instance I'd like to participate in. When I sub to the thread from sh.itjust.works there are no comments; I assume that's because sh.itjust.works only starts syncing communities after the first subscription. So now I can either read the thread on an instance I don't have a login for, or participate in an empty version of the thread on sh.itjust.works.
Is there any way to participate in the active thread at this point? Thanks.
edit: Just checked my subscription to the new community is [pending]. Maybe that's it?
edit2: Thanks to @Barbarian I can at least sub to one of the pending communities, and the others are on lemmy.ml, so I'll just wait those out.
