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.
SD card>paperpeile
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.
