Missing Scan

Scanned a document a few days ago using Adobe Scan app. when I scanned it I was so proud of how clear and good it looked, so I folded up the paper and luckily decided to keep it. Unfortunately, went to retrieve the pdf tonight and MISSING. I rememebr scanning it quick and I have a feeling I  never hit save pdf. idk if it temporarily saves them when going to another app on iOS   But I know I recently closed all my apps. Can’t find the file. So I thought I would suggest that an update should auto save all PDFs that were not “saved” by tapping save pdf and put them in a folder called “temporaily saved” this would be a life saver, literally.

thanks
