saved scans as pdf from adobe scan after cleaning up but app crashed

Using adobe scan app  on android phone. worked last week. today when i pressed save as pdf after cleanig up the scans, it said something went werong and offered to ssave them as jpegs, to which I agreed.  Then the phone memory was all used up, it was the adobe scan app with 10.72 gb of user data. It was 0 gb of user data before I scanned the 180 pages. 

I went to get the files somehow. I am signed in under the same email address I used all last week successfully getting scans done with the app.

1. on the phone. since it shows 10.62 gb user data, I assumed that is the scans. But they must be in some hidden folder, because I cannot find by searching around in the phone after plugging it into the pc. So what is taking up the room? Or where is the file?

2. I thought they would be on the cloud. It say they will be uploaded to document cloud when you say save pdf of your scans. which I did. I also read it automatically uploads everything youscan to the cloud, I know because many were complaining this was being done with confiedentail work docs. Anyway, I went to all the addresses they tell you to check. I looked under "cloud documents" in the files but only old ones.

3. chatted with tech support and after trying all their steps they said to come here and type my question.

So how can I get to the user data on the phone that the adovbe scan app is taking 10.62 gb of memory to store. (it was zeroed before I started my scan job of 180 scans today)

or

will the cloud docs maybe show up later?

thanks
