Can not find specific word in Viewer with annotation of Paperpile

Very comfortable using Paperpile a few months ago. However, I have not been able to use the search option in the PDF file viewer, I think it is poorly implemented since it comes out of the browser area.

Does anyone have the same problem or is it my mistake?

I am having a similar issue! I think the search actually works, but I can’t see what I’m typing into the search bar.
