(sorry if that has been already reported, but the forum search function doesn’t work to take me to places where a keyword is used in the thread, and this thread is way too-long to scroll through).
I’m using Android 8.0, and the latest verison of the Paperpile beta (I believe, no version is reported in the ‘About’ section of the app).
Most things are running smoothly, however one annoying cosmetic bug is that after downloading a PDF to my device using the ‘share to Paperpile’ button in my brower (Chrome 78.0.3904.96), the notification that the PDF is download is complete (in the Android pull-down tray) is not able to be removed unless I reboot my phone. I.e. I cannot swipe the notification away.
Another slight bug-bear is that it’s slightly annoying that you have to wait quite a few seconds for the reference to sync - so I have to stare at the spinning wheel for quite a while - I would be happy if this happened in the background (or as a tray notification), so I can continue reading/working in the browers.
