It appears to be working now. I think it is similar to how it took a few days for the community to become federated at all (I could not access it from lemmy.studio for a little while after I created it).
I think it is still is useful, as some software still hasn't figured out how to turn on numlock automatically, and for a few applications number pad scrolling can be better than the arrow keys, but it is probably less useful than the scroll lock key at this point.
I was just wondering when you would update to 0.18! It turns out the client Jerboa requires version 0.18, so I was just about to post asking when you were planning to update as it seems to be a pretty nice client. I should also be able to finally set up 2FA, which I have been wanting to do for a while.
I am not sure, I found it in the woods (I'm not very good at identifying these criminals).
Now it appears to be working for me too, so it probably just took a while to become accessible through federation (it was only created a few days ago).
PeerTube is a great one that is also part of the Fediverse.
