I guess it has something to do with how active the community is. I had the same issue, and was trying to troubleshoot with Ruud why this happens. Today in the morning, my community started being more active and started to appear on other instances.
Make some posts in the community (and comments), invite users and after 24h, it should be visible to other instances as well. Could be a bug (because Lemmy is riddled with bugs).
Did you assign e-mail address to your account? Are you using it for login or the username?
Anyone else having issues with login on mobile devices? I can’t login at all, but I can normally enter on desktop. Tried in Brave and in Chrome, it doesn’t work–after pressing button it keeps loading forever.
EDIT: turns out I kept entering the wrong password entire time. 🤦♂️🤦♂️🤦♂️
Well, we won’t miss anything if we move everything here. 🤷♂️
That was the main reason why I switched to lemmy.world; never looked back. Plus, Ruud (the admin of this instance, runs also a Mastodon instance) and actually upgrades the server so it can handle all new traffic. Lemmy.ml is often down because it can’t take the heavy load.
