Hmm... somebody else reported a similar problem. I will check this shortly.
Make sure you don't have an ad blocker running. Please check in the console if there are any errors and follow the info to check if there are any errors in the background.
I'm fixing this for the next release...
Sadly, it's impossible to do something like this since there's no API to manage DS users.
Users under DS are managed like other documents under Google Docs.
I was thinking of an a better/easier alternative:
It it close, but sadly, DS doesn't allow you to sort by the "delta" column or turn it into a heatmap to easily spot the major changes. But still, I think it might be easier to find the major changes.
I know it would be possible to create exactly what you are looking for using Tableau and some calculated fields.
I just made a fix which will be available in the next release.
A new version was released on Thursday, February 27 - please let me know if you still run into this issue.
