Where is my Canon scanned pdf?

QUOTE FROM AN EARLIER POST I scanned a document using my Canon app and chose the option to save as a PDF to my mobile device. I can't, for the life of me, find where it is stored - it isn't in iBooks or any other PDF reader I have on my iPad. UNQUOTE

Here is a better answer that actualy works.. when the image shows up on your Canon app you need choose ‘use as pdf’ and then-the next pull down (from the Canon App) choose the ‘open in other apps’ option and choose ‘copy to iBooks‘ option

NOT the ‘save to mobile device‘ which would be the natural choice but DOES NOT WORK....

This fix works with ios 11 ok.
