Deleted files in scrivener IOS app

Hi all
I have just downloaded the app on my iPad (iPad 5 the latest iPad) and still learning my way around.

I have also downloaded Dropbox as requested and whilst i thought i had saved my story (the first 3 chapters started on it) i seem to have deleted the wrong story and now i cannot find it anywhere. It’s not in the trash bin and i have been on Dropbox and its not there either…

Can anyone help me retrieve these files please? Otherwise i have lost the first part of my story. :frowning:
