Certain (annotated) PDFs not opening

On Zotero 7.0.10 for Mac, certain PDFs which I have imported after annotating them on my Kindle Scribe are not opening properly. They open and display fine in Preview, on browsers, etc., but Zotero seems to not be seeing them as a proper PDF file.

Sorry, I have posted with the Report function now. I would delete this thread if I could. edit: nevermind, I've been told to put the report number here, and have done so.

No, we can stick to this thread — I've deleted the other. A descriptive thread title is always better.

Although it opens fine in all the PDF viewers I tested, the file is still corrupted. I was able to fix it by going to File → Export and selecting the “Create PDF/A” option in Preview.

It would be good to report this issue to the PDF.js developers, but since the file isn’t freely available online, I’m unable to do so.

Ok, thanks. Yes, it looks like saving it as a PDF/A file fixed it for now. Thanks!
