Has anyone else had issues interacting with the lemmy.world instance?

Previously when I was trying to subscribe to a community it would just remain pending, until a couple of weeks later when cancelling it and trying again worked.

Now I’m finding I can’t post there either. The ‘Create’ button just spins interminably.

Are they just getting smashed by traffic? Am I better off waiting until certain times of the day to interact with that instance?

UPDATE: I checked the POST request in the inspector (which I should have done before posting here) and it turns out it rejects posts where you specify the language. It gives a 400 response with a JSON body of {"error":"language_not_allowed"}. Hopefully the Lemmy devs get around to giving the front-end some kind of feedback about that rejection soon, I can’t be the only one running into this.
