Although I have checked fast web view in an ES4 Designer (dynamic PDF) form, when I upload to my server and view in FF or Chrome using an Android device, it does not display online (see below: works OK when using a Windows desktop).
It asks to download the PDF form and tries to open it in latest Acrobat Reader DC, but then shows an error when trying to open and view: "Please wait...If this message is not eventually replaced by the proper contents..."
I also used Google Drive to download a copy of the same PDF form onto the same Android device (Nexus 10 tablet-OS: Lollipop 5). Same result.
As mentioned this same form works perfectly on Win 10 Desktop when previewed in ES4 Designer or Acrobat Pro DC, or uploaded and viewed online.
Not sure what I am doing wrong? Any help appreciated.
