What is subscribe pending? A bunch of sublemmies say that instead of 'subscribed'

It's a bug with the newest update. You're still subscribed afaik.

It's been really buggy here lately :/

For me it just means "yeah youre subscribed and will get the posts in your feed anyway but your base instance isnt very sure in its acknowledgement"

in short, for me it means nothing

Where are you trying to subscribe from? Lemmy or mastodon/friendica/calckey etc?
