Whenever I try to open secure form PDF files on a webbrowser with the adobe acrobat reader app, I get an error message that says the file cannot be downloaded please save the file to your local storage and try opening it again. I use the andriod 8.1 Oreo OS platform. I tried changing the permission on the app., I tried uninstalling and reinstalling the app I also tried to change the storage permission on both of my web browsers google Chrome and Firefox. What seems to be the problem with the adobe reader mobile app.
