From what I can tell it just gets stuck on your default sort mode, for example I can’t switch off of Subscribed+Hot

Is there a GitHub issue to track this?

As cool as it would be, currently federation doesn’t work in this way

Basically the two communities you mentioned are [email protected] and [email protected]; notice that when I write it out like this, they have different full names.

If you post on either community from any instance it will federate to that community on all instances but not between each other as they are separate communities

Hopefully this helps, I’m not great at explaining these things 😅
