Updated Reader - now can't see what PDFs look like
Acrobat Reader updated today - now it says it is Adobe Acrobat Reader DC and has a black icon. Yesterday, PDFs in a folder when displayed as "medium, large or extra large icon" showed an image of the pdf. This function is crucial as we need to see at a glance the differences in drawings (say... "5281-02 and 5281-02-172") we store as PDFs. Today all that displays is the logo icon, which is useless. I cannot find an instruction or preference for display to show the document, not the Acrobat logo.
Is there such a direction, and if so, where or what is it?
If not, how do I get back to yesterday's Reader and the icon images I need?
Thanks all.
