Lost a very important 100 page scan

I recently scanned about 100 pages, which were saved into Adobe's Cloud. After trying to send the file to a friend, the Adobe Scan app gave me an error, crashed, and sent me back to my iPhone's homescreen. Opening the app again, I discovered that the scan was no longer there. I went on my laptop to check through my files on document cloud and it wasnt there, or anywhere else. This is incredibly frustrating as I no longer have access to the content I was scanning as it was from the British Architectural Library, and it is of utmost importance that I retrieve this lost scan. Can someone help? Surely it is floating around somewhere in Adobe's system, and if not this will be of massive detriment to my studies. I will no longer use Adobe Scan if I found out I have indeed lost this item.
