I have a digitally signed document which after using the steps to Trust the signature displays a valid signature on top of all the signed positions in the PDF. In my earlier experiences, the document in these cases will display a tick mark on the signed positions. But, this document states valid signature if i move the mouse over it, but doesn't show the tick mark, instead the entire "Digitally signed= ... all the way till timestamp" is being displayed. Needing assistance on why the tick mark is...
