Ape Apps

I've used the app successfully before, but am getting this same result. I scan a document, but nothing appears on the screen. Last time I tried several things (restarting, etc.), and only when I uninstalled and reinstalled did it work. Now it's back to nothing showing up after a scan. (The pages go through the scanner, and everything seems like it's working -- just no document produced.) How do I troubleshoot this? (Using Windows 10, PDF Document Scanner v 4.13.0.)
