For instance, I made an account here in Lemmy.world because it seemed like a nice, well rounded place to start. However, I want stuff from TTRPG.network to show up when I browse my “frontpage,” but all I see is my Lemmy.World communities.
I’m using Liftoff on Android at the moment, but I’m a newb, so I’m clearly not tied to that app.
You should be able to switch to the “subscribed” or “all” feed from the top in the liftoff app.
