Then when you allow it too, it complains the file isn't accessible. That I should check the connection or the file name is too long. It isn't.... It is a local file in my downloads directory. Other programs and read the PDF just fine.
Sorry for the delayed reposne. I would like to inform you that we have released new version of Adobe Acrobat Reader Mobilei.e version 21.10.00. Please update your application and let us know if still face the same issue.
