Ahhh, figured it out thanks to @eocanha here: https://www.ads-software.com/support/topic/few-posts-listed-solved/
What he didn’t say was where to put the code.
Do NOT use a plugin like “My Custom Functions” because that only ads functions to the core WordPress functions.php page.
You need to add it to the Share a Draft functions page: (shareadraft/shareadraft.php)
You find it here on the left hand (black) panel:
Plugins -> Plugin Editor
Then look on the dropdown menu on the top right of the screen:
Select plugin to edit: -> Share A Draft -> hit select
There you scroll down and find the “get_drafts()” function and replace it with the one @eocanha provided.
(you probably should be cautious and save a copy of the original in case something messes up).
Hopefully, the plugin editor will add this code to the next update. Otherwise we will all need to repeat the process then I suppose.
Hope this helps.
