BUG: Acrobat Reader DC MUI v24.002.20687 always opening documents in "Protected View" doesn't confirm user that a Digital signature exists
Acrobat Reader DC MUI v24.002.20687 that is already configured to always open documents in "Protected View" was unable to confirm me that a Digital signature was already existing in a digitally signed document (I even checked Document properties with [Ctrl]+[D]) that when instead opened with Microsoft Edge Enterprise v109.0.1518.140 (Official build)(64-bit) immediately informed me that "This document is digitally signed. Some signatures couldn't be verified. View signatures" and so it immediately allowed me to see what was digital signature.
Now I understand that 'Protected View' is already a security feature and that also has some limitations (I even found that I'm unable to print if I remain into 'Protected View') but if a document source is well known (just think about of documents shared by a Ministry of a specific country) then is completely unacceptable that end user is kept unaware of such already existing digital signature for document he/she has just opened.
