When I open a PDF, it opens in the tablet with Acrobat and I can see it immediately and use it, no problem.
When I tap on the right side I can access all PDFs by next tapping Top Left corner and I see a list of recent documents.
How do I wipe out this list as many of these documents are no longer on my google drive but are still shown on the Recent documents
Have clicked on Settings but no Trash Can displays.
Have also tried to Hold Down finger on one of the many items in Recent documents in the hope that a Delete would show, no such thing.
