@joshshaked let's see - looking into it, this thread was on Mastodon, and Mastodon does not include the 'totalItems' property in its ActivityPub payload, unfortunately4 replies was the entire collection at that time.It brings up another point about _subreplies_ - something ActivityPub doesn't do well at the moment.Most implementations will just return direct replies (if they return replies at all) in AP, the client is forced to enumerate each reply, recursively, for the entire "thread"
