Detailed description of issue
A client of ours is working with a large 130 page construction drawings PDF (80MB). It loads fairly quickly when it is fresh without any annotations. But the current state of this PDF for them has more than 50 annotations and comments, and it takes more than 40 seconds for it to load. And after loading for an initial 10 seconds, the browser freezes, further confusing this client. Once I get a browser popup saying the page is unresponsive, if I just click wait it eventually loads after about 40 seconds.
Does your issue happen with every document, or just one?
It happens with every document that is this large with this many annotations.
