Interesting to read this issue you are having.  That is the error I am getting.  I am the admin and the user and am not able to sync only let in to use the app.  Incredibly frustrating.  I would much appreciate a resolution to this [evidently] ongoing issue since TSheets became QB Time.  I understand glitches and issues and am very patient.  What is very annoying is how difficult it is now to get support.  TSheets was wonderful and very accessible.  Please help us all be able to use this app or we will have no choice than to make other choices.  Thank you, I look forward to a prompt resolution.  I have new employees that are unable to track time because I can't sync allowing QB Time to see them.  Please & thank you.  Kim
