Please make sure you have "undetermined" selected in your list of spoken languages in your lemmy settings in addition to any other languages you speak.
Most lemmy content does not come through with a language tag, and you need to have undermined selected as an option to see that content.
Mods can set languages per community to, so it's possible that the communities in question haven't configured their languages correctly?
Ok ty, I'll let them know when I see it. Ty for bearing with me since sinny new to Lemmy :D
