There doesn’t appear to be an option to share the paper pile link for an article you have stored in paper pile from the mobile app.
Is there a way to do this?
If I open the web site in Chrome on my device I just get the modal dialog to open the mobile app, which doesn’t help.
(And yet the article I want to share is right there behind the dialog box!)
Sharing features have not yet been ported to mobile; we will first update our entire sharing system (check out our roadmap and this survey about sharing) and then bring it across platforms. The update is scheduled to be implemented on web by the end of this year, so work/updates for mobile will follow after that. In any case, I have added your +1 to the topic on our internal tracker.
