Summary

If you browse with show read posts enabled, and read every post on page 1 of content, when you navigate to page 2, it will show you page 2 of “unread” content, and you need to go back to page one.

Steps to Reproduce

  1. Disable “Show Read Posts”
  2. Browse a community
  1. “Read” each post on the 1st page (e.g. upvote all of them)
    • Pay attention to top couple of posts on page
    • Notice vote counts at bottom of page
  2. Browse to Page 2
    • Notice large drop in post vote count between end of page 1 and page 2
    • Pay attention to top couple of posts on page
  3. Browse back to page 1
    • Notice vote counts at top of page and bottom of page aligns between the end of the original page 1 and the viewed page “2”
    • Notice Page 1 content is different from original page 1 content

Technical Details

I believe this is a pagination issue when constructing the offsets used for pagination, there may need to be a mechanism to deduct or track the state of read posts.
