On iPad, on the top screen toolbar if you see two circles with lines next to each, one with a checkmark possibly. Click on that and then click the more icon (circle with three dots) and scan should show up there. Each new note seems to go back to the original setting so I have to do that for each new note that I want to scan a document. Hope it works for you!
