How to subscribe to a community in another instance?

AskThinkingTim@lemmy.world to No Stupid Questions@lemmy.world – 3 points –

When I subscribe in a community in another instance it always says "pending " in yellow. I can comment but I am not officially subscribed to the community. E.g. subscribing to "!nostupidquestions@lemmy.ml"

Maybe I just need to wait.

Edit: It says "subscribe pending" in yellow
