More than 300 scanned documents are completely gone.

On November 8th, I scanned about 300 documents directly on my cell phone. After that, I edited everything such as cutting and rotating. Then, I saved it by pressing the Save PDF file button in the upper right corner. The problem is from then on.

Perhaps because of the large number, the message "It's lagging and uploading" didn't go away. Then, as it was, all of my 300 documents disappeared. Isn't it really real? It's like 300 pictures.

So I contacted Adobe Engineer and looked for the document together. I went into Adobe PC Cloud, Mobile Adobe Scan App to find hidden files, and my mobile phone device document box, but there were no 300 of mine anywhere.

In my opinion, the Internet was not smooth while it was being stored, or it was not saved due to external factors. As I expected, there's no way to find it, right?

If you know how, please let me know. I think my wrist is going to break.
