I can reproduce this with 2.9.0.beta3. The docs index appears to default to recent activity, and doesn’t sort by pinned status; it does, however, show the correct pinned status by icon.
I pinned the first doc I created, hence it is the “oldest”:
I updated the pinned doc, making it the more recent activity:
And added a new doc, which then becomes the most recent:
I changed the pinned status on the topic (meaning the discussion, the “docs view” does not show the pinned status).
And it updated on the docs index:
Notes:
- I tried a category and global pin: same results
- Any activity bumps the doc in the index: the more recently discussed topics will be at the top
