Think I’ve finally figured out why this has been so confusing for me, and it might be a tiny little bug(?)
Thing one: short videos with the ‘short video’ tag aren’t being hidden by the intelligence system.
False: they are, within the window of implementation as you described. So, working as intended… however!
I think the ‘more from this site’ text / divider is missing for the ‘Story Categories & Tags’ section where the tag is available for the feed, but doesn’t belong to that current story. This caused a lot of confusion for me when you mentioned the tags not being applied retroactively, because it looked to me like all short videos have the tag and so were being applied retroactively, like this:
This screenshot is from a short video which I know 100% does not have the ‘short video’ tag, so it should read ‘more from this site’. Similarly, this screenshot is from a non-short video, as you can see:
There is no ‘more from this site’ text!
Much less important thing two: it looked like some shorts were missing the ‘short video’ tag on first import.
Managed to reproduce this today:
The ‘Story Categories & Tags’ section is missing, but only until I refreshed the page. When I refresh, the ‘short video’ tag for the site (whether applied to this story or not) appears as expected. A non-issue I think!
Hope this helps
