We recently upgraded to QBO advanced and discovered Spreadsheet Sync. How many users are able to use Spreadsheet sync? Can multiple employees use it, or just one?

I was playing around with Spreadsheet Sync on Friday and things were working nicely. My manager logged in and started playing around with it on Saturday. Now (on Monday) I can't get any data to pull, and when I tried to log out and log back in, I can only log in if I take admin rights away from my manager for myself.
