Lemmy Support

Many instances say to keep language settings as "undetermined" otherwise you won't see most posts Example: https://lemmy.blahaj.zone/post/59161 Example: https://reddthat.com/settings

Yet when I try to post a comment it will fail with language_not_allowed because initially there is no language selected. So I need to click on the "Select language" drop-down and choose English (the only option)

Actually in the Lemmy web interface (at least on my instance reddthat.com) the Post button will spin endlessly with no indication of what's wrong. Using the Jerboa Android app there's is the very brief error message language_not_allowed, and the comment disappears so I have to type it out again! On the Jerboa app there's also no option to select the language for the comment, so I can't use it to comment at all.

I experienced this language_not_allowed error while commentating on gaming@beehaw.org and lemmy_support@lemmy.ml , both English language communities

So how is this language setting supposed to work?

Is the language selected for posting comments the same setting as the profile setting, which the links recommend to keep as "undetermined" to be able to see (English language) posts?

Have i encountered a bug? Specific to my instance or Lemmy in general?
