Oddly enough, I just ran across a new community to subscribe to on lemmy.ml, and that one went right through. I also noticed another oddity (which is probably related directly to the subscribe bug)… the first time I click the subscribe button, it turns dark. If I click it a second time I get the Pending message. However for this new community, I clicked the subscribe button just once, then reloaded the page and it said I was subscribed. Going to try that with some others and see if I have any better luck.

[EDIT] I do seem to be making progress now by reloading the page. The first one took some time, and it seems like subscriptions are going slowly no matter what server they’re on right now. I’ve seeing several that don’t even show the subscribe button until I reload the page again a few minutes later but I’ve been able to get fully subscribed to all the groups I’ve checked again so far.
