Hi there! Looks like you linked to a Lemmy community using a URL instead of its name, which doesn't work well for people on different instances. Try fixing it like this: [email protected]

I don't think the issue is your profile but the community in which you're trying to comment into.

The community mods are able to select which languages are allowed in that community. If they're not careful and unselect Undetermined. or they only allow Undetermined, it will lead to that error when trying to post from an app that doesn't define the language of the comment/post, or if the app tries to assign a language that isn't allowed by the community.

Sadly I don't see any simple way to view which languages are allowed by a community unless you're a mod there.
