"Sharing" a link - Link does not work correctly

I am having issues with the “sharing” link on Kami. I have annotated a PDF document and shared the link with my students. Last week, the link works fine and students can view the PDF and my annotations, but this week, when they go to the link: https://goo.gl/hLGHbK nothing shows up (except the Kami website). The annotated PDF is no longer there. I’ve tried this on two different computers. Please help.

Hi dsoodijinda,

Can you please email support@kamihq.com?

I was able to open the document, so we will need to examine the issue more closely.

Thank you
