App is successfully installed on my device, and also synchronized with my Paperpile account.
And when I push the download button, PDF file is also successfully downloaded on my device.
However, after I push the PDF file button on app, PDF file cannot be opened and big X-mark is shown on app screen.
I use the SD card in my device as external and default storage.
Therefore, PDF file is downloaded to the below folder.
Downloaded PDF file in this folder is successfully opened with the other app, for example Adobe reader and so on.
For the information, my device specification is as follows.
- HUAWEI MediaPad M3 Lite
- OS Android 7.0
- SD card in use has 207GB free space.
