Paperpile app for iPad long freezes after pencil annotation

The app freezes only after closing a PDF which recently is annotated with pencil (this doesn’t seem to happen with normal highlighting).

Thanks for the report, @phizaz. Does this happen every time with pencil-annotated PDFs, or intermittently? Are you forced to restart the app in order to continue using it in those cases? Any details will be helpful for the team.

It happens consistently, I presume that the freeze duration is proportional to the amount of pencil annotation (but I did not verify this).

I generally did not force restart the app (lest I could lose some annotations), I just waited it out, after some time (few minutes), the app unfroze, and continued to work as usual.
