Can't open PDF with alternative apps on Android

When I try to open a PDF of a paper in the android app with paperpile’s own PDF viewer and then try to open the PDF in an external app, I get the following message and cannot open it.

“There are no applications installed that can open PDF documents.”

My environment is as follows

Model: Pixel 6
Android version: 14
Paperpile app’s version: 1.3.8

The following apps are installed as PDF viewers:

Thanks for the report and details. There might be some permissions configuration or something similar in the device blocking the function, we don’t have a Pixel on our end to try/share specific advice but I would recommend having a look around Settings, as well as uninstalling and reinstalling the Paperpile app just in case. Let us know.
