I have the same issue but the communities appear both on my feed and my subscription list, so it's probably a visual bug.

Give it a bit and they will become active.

I think it may be a visual bug. Happens to me too. When I first click "subscribe", seemingly nothing happens. If I click subscribe again I'll get stuck on "pending". If I leave the page and go back I'll see I'm not subscribed, but when I look at my subscriptions I'll see it there twice!

I've started clicking subscribe and then just leaving the page. While the button doesn't react, it does seem to be working.

I've been getting the same thing as well.

I'm still stuck on subscription pending for a bunch of communities. I see this both on the community list, and on the individual community pages themselves. Perhaps mods need to approve new users?

Yeah I’m having issues as well. I’ve been waiting to see what happens.

My main feed is now mostly just gaming unfortunately

Same here. I’m hoping it’s just a bug: I subscribed to so many like this and hoping it still goes through otherwise I’ll have to go look for everything all over again

Try unsubbing and subbing again, worked for me when it happened.

I definitely think it's possible, I am having similar problems.
