In addition to Bimpe's reply, we also need to understand if it is a browser specific issue or it is a permission issue here. Could you do the following?
1. Clear the browser cache, close the browser(s) and try again?
2. Try to login using other browser?
3. If your colleague log in in your browser, can she(he) is seeing the "new > dashboard" option.
What is your colleague's OS/browser compare to yours?
