Hello, I've been using Adobe scan for about a year for free for the help of my office work with my iPhone.For that purpose, today I scanned about 90 pages of a textbook (since my job is a teacher) and even after it, there was still some pages remaining so I continued scanning. However, while doing it, the app suddenly froze and I couldn't do anything to it.So I restarted the app, but at then, I found all the documents I'd saved deleted and they weren't found even in cloud services. I put a lot of time and effort in it, so I keenly want the issue settled as soon as possible. I am not sure if you can tell the situation with my broken English (because my first language is not English), but hope for immediate help.Thank you,
