All communities won't show up on instances automatically so it may be that you're the first person on your instance to 'subscribe' to that community! In my experience with lemmy, you can simply add /c/community_name@instance.tld (TLD=top level domain) to whatever instance you're at and that should pull that community in, but it could take a few seconds.
This example url would access the /c/general community @lemmy.world from lemmy.zip:
lemmy.zip/c/general@lemmy.world

Apple Music has become my main 'first stop' after Spotify's latest UX overhaul. I've also started buying physical CDs again because I've realized the importance of physical copies. Never got into vinyl but I think the CD boom is still to come, ha.
