Hi, I recently encrypted a file through certificate encryption on my PC using Adobe Acrobat Pro DC but unfortunately when I try viewing it on my mobile devices (tablet and smartphone) using Adobe Acrobat Reader DC, it gives an error message that says "The document has features that are not supported in this version of Adobe Acrobat"

How do I open the file?

My mobile devices have the latest version available on Google playstore. I created numerous certificates changing versions of Adobe that can open it etc so as to try and make the file compatible on all my devices.
