One of my recent posts (link) has 26 comments, but on both lemmy.world’s web site and various mobile apps I only see 3 when logged in. I can see the missing comments in Inbox/Notifications but not the thread. If I log out, I can see all the comments.
Is it set to just unspecified? You can select more than one language (or all of them). I’m thinking you might not have English selected.
Can you see my other comment replying to your comment in this post?
It looks like on the post you originally referenced there are 4 with language unspecified and the rest are all tagged as English.
Ah, that fixed it. Many thanks.
