Have you the opportunity to send the PDF file which rise the issue?
It could be a very large file on a low performances device or a very complex file we would like to investigate on.

Thanks for the quick response. Unfortunately no, we don't have the sample PDF files producing these ANRs, just the ANRs themselves. We had about 30k screen views yesterday for this activity, and we only get back the dev console ANRs, not the PDFs that produce them. We have about a dozen of these ANR reports.

At this point, we're just looking for what could be the cause so that we can be mindful. From what you said it could be a complex PDF or a low resource device. We can go with that for now, and we'll see if we can get further feedback from users.

Lastly, I believe these ANRs could be related to corresponding crash reports. Unfortunately, these reports from the dev console aren't very helpful, but I'll post the backtrace that we're given if it helps you at all:
