Curator only pulled in 25 Posts. Can I go back further?

In short, No you can't go back further :( 

Unfortunately, due to recent API changes, this is no longer possible for particular sources. 

The limit of 25 posts helps reduce strain on our servers, especially for Sources or hashtags with thousands of posts.

 Your Source will refresh regularly, pulling up to 20-25 of the most recent posts each time, keeping your feed updated with the latest content.

If you’re using Facebook Page, Instagram Account, or Flickr Album sources and are on a paid plan, you can email us at support@curator.io. We can manually attempt to load those other or older posts that weren’t pulled due to the initial cap.
