Annotation not working on iOS (iPad)

Hi, I’ve been using paperpile for few years now and the experience so far has been very positive.

Today, I opened up a PDF on Paperpile iOS app (iPad) and tried to annotate.
However, the “annotate button” (one with the pencil mark) does not activate.

I’ve tried this with both my finger and apple pencil, and on multiple PDFs.
I’m suspecting this might be a bug, is there any way to solve this issue?
Many thanks in advance.

Welcome to our forum, @Ren! Is this still the case? Have you restarted the app, perhaps signed out/back in? We haven’t had similar reports so far – if the issue persists, please share a screen recording of the issue for the team to investigate (here or via chat/email – support@paperpile.com).
