Commenting suddenly unavailable on mobile apps due to security settings
I've been creating PDFs with the same security settings for years. I restrict editing and printing of the document, but allow Commenting, Filling in form fields, and Signing existing signature fields. This has always made it so that my PDFs cannot be changed or reassembled, but can still be annotated with notes and highlights just as I need. Just in the past few weeks I've found that Commenting does not work on my PDFs in the Acrobat app on mobile devices only. Commenting works as usual in the desktop application, but i have tested in the mobile app on iPhone, iPad, and Android and now commenting is no longer enabled, even though my security settings have not changed in years. On iPhone and iPad, the edit icon is completely gone. On Android, the icon is there but I receive an error message when I click it that says "This tool is not available due to the document's security setting." If I remove my security settings, I then have access to com
ment again on mobile devices.
Here are screenshots of my security settings. You will see that Commenting is allowed. Why is it that suddently commenting is not working on mobile devices? How can this be resolved?


Thank you!
