Not allowing me to sign more than two pages and then the document disappears.

Hi,

I have tried to e-sign a document sent to me on Adobe Acrobat, but I can only sign the first two pages. The document then freezes and I am not able to see the rest of the pages or click on the empty feilds. I've tried doing so on Chrome, as well as Safari on both my laptop and phone. Please let me know how to fix this.
