I have a PDF I wrote that contains a great many short video clips (over 100) of sentences in ASL (American Sign Language), and I'm currently testing it for its anticipated readers. To prevent the annoying "This may damage your computer" warning for every single one of them, I can tell my readers to go to Edit > Preferences > Security (Enhanced) and un-check Enable Protected Mode at startup. But that leads to a warning this this will also disable Protected View and App Container". To help me reassure my readers, do you know if this warning applies only to PDFs or does is apply to other apps on one's computer? And what is App Container?
(When I try the other method of saying Add File to add the file name of the PDF, that doesn't seem to work.)
Thanks in advance for your help.
