How to use Display Order

[olevelo]

You would need to rescan and replace all metadata, IIRC, to get the new order to show up immediately.

I did that every time.  Multiple attempts.  It worked for the DVD/airdate (though there were some weird inconsistencies), but it didn't work for the new Story Arc episode until today.  And I just made some changes to the Story Arc in TMDB but it's still not picking it up in Jellyfin.  Seems that the API doesn't make it available right away, but no idea how long.
