Acrobat on Samsung Tab A - Folders not Displayed

Hi all...

Just bought an 8" Samsung Galaxy Tab A for inexpensive -- it won't kill me if lost oir stolen -- and easy travel travel transport. Unlike on our full-size iPads, the Acrobat app does not seem to display a tree of folders. It only displays all the files, merely sorted by folder. This, of course, is problematic when I have over a hundred files on the device. Organizing them in nested folders doesn't help much.

Am I doing something wrong -- is there a setting I can change -- or is this a feature that needs to be improved?

Thanks in advance.
