If you're missing replies on posts, check your language settings (details in post body)
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.
I have undetermined and english selected but I have a post where it says there are 3 replies but I only see 2. Does this definitively mean someone has commented with another language selected? Or could it be someone commented and deleted their reply or something else?
