When subscribing to a community on another instance, the subscribe button will change to “Subscribe pending”.
This appears to be a bug, as the content you’re subscribed to will appear anyway.
You can follow this issue in the issue tracker, as well.

I have experienced this issue from my instance but only when trying to subscribe to communities on lemmy.ml. I’ve been able to subscribe to communities on this instance and some of the larger ones like sopuli and beehaw.
