John: Your understanding of the time-tracker is incorrect.
It is not something that you will see in a browser. It is a desktop application that you download to your computer and launch.
re: "Thanks but I have downloaded the desktop app (and reinstalled it twice) and it still doesn't work."
It is working well for me.
What operating system are you using?
I checked and could see that you already have an support ticket created regarding this issue. I will share your report with the team handling your case and one of our agent will follow up with you as soon as possible.
