How do I combine the pages in my pdf in the right page order
When I had Acrobat 8 I was able to scan my docments, add the scanned documents and then combine them in the right page order by having my documents in a list and there were two arrows - one down and one up. If there was a page out of order (usually "2") or (the first image file), I was able to click the up and down arrow and put it in its right place. Then create and save. My Adobe Acrobat 2020 doesn't seem to have that option.
