There might be a case when you see your files in iCloud, but the folder's name is not Scanner Pro.
This is happening because four of our products (Scanner Pro, Scanner Mini, PDF Expert, and Documents) share the same iCloud container for the document flow. iCloud selects the icons and names for the folder randomly for each device, depending on the order of the apps' installation and their connection to iCloud. It considers all four apps as one because of the shared container.
Thus, you may need to check either of these app folders in iCloud to see if you can find your files there.
They still display the content of your downloaded app, but with a different icon and name, as it is considered the same one.
We understand the confusion this behavior might cause and hope that it will be changed in future iOS versions.
