Thank you for the feedback. We have made performance and session improvements which should now resolve the issue. If in case you face the issue again please feel free to reply back.
I regularly have the same problem. I'll be in the middle of editing a template or otherwise working with a document, and then suddenly I get the circular time-waster with the announcement that "Adobe Sign is Loading" -- which means everything I was just working on is now lost. This happens so frequently that I don't even have time to save between changes. I have the latest version of Chrome loaded, and running this on Windows 10, 64 bit.
