If you have lost a story, first look in "My Stories" which you can get to:
On desktop - on the left sidebar
On your teacher PWA app - near the top on the menu page
In your teacher portfolio
My Stories has tabs for all, draft, published and pending stories.
If your story is not there, try story search.
You'll notice on the left-hand sidebar on the desktop version of Educa (note, it's not on the PWA) a Story Search icon.
There are a number of options available to define your search. Make sure to choose a generous date range at the top and then enter a keyword preferably a word that is in the title. Then click "search" or press return/enter to see a list of stories you have permission to see.
Lost in Story Approval?
Finally, if you see a "Submit for Approval" button at the bottom of your stories that sends your stories for review, it is sometimes possible that your reviewer has edited the story in a way that changes who can see it. The best course of action here is to ask a person with Educa "site admin" access to look for your story, as they can see all stories.
