Does anyone know why I can't view certain PDF files (ones that i have created on my computer and saved to my server) on my Android device (Moto X Pure)? I can view other PDF's on my device, just not these, and other mobile devices are able to download and view without problem, both Android and I-Phone. It says can't open file. When i try to go into Adobe and open from there, there files are grayed out as if invalid. Again, it's working on other devices and I'm able to view other PDF's not from my server.
I want to be sure I understand the issue you are having. You mention both the iPhone and Android apps but I'm not clear where the problem is happening. Is this happening on both the iPhone and Android, or is this just happening on Android? Thank you!
Would it be possible for you to attach a screenshot of the page where the files are 'grayed out'? What is the error message that you receive when trying to open the files directly from the file browser? Could you please provide additional details such as the Android version of your device and the source and the location where these files are present?
