PullPush not indexing newer threads? (1–2 month old posts return nothing)

Trying to understand if this is expected behavior or if I’m missing something.

This is a ~2 month old thread: https://www.reddit.com/r/netflix/comments/1rmx8bh/netflix_has_10000_titles_and_somehow_shows_you

PullPush returns nothing for it: https://api.pullpush.io/reddit/search/comment/?link_id=1rmx8bh&size=10

But for this ~1 year old thread: https://www.reddit.com/r/netflix/comments/1kif3wc/a_deadly_american_marriage/

PullPush works fine: https://api.pullpush.io/reddit/search/comment/?link_id=1kif3wc&size=10

So does PullPush only archive/index older Reddit data, or are newer threads/comments supposed to be available too?
