In your case, if you only see a couple posts, you likely have bot posts disabled. Or if there are none, you could have blocked it earlier on, check your blocklist on the Settings page and click "Blocks" as you might have blocked it to clear spam on the local feed.

If you still see none at all, it might be a Voyager issue (a length limit edge case possibly?)

For people accessing it outside of lemmy.ca, it may be because no one on your instance has subscribed to it yet, so it's not federating the posts.
