The resource is not present in our Time Tracker Group which has Timesheets-Navigate access rights but still she is able to see Timesheet option under Home. We recreated this issue and checked that without the Time Tracker group one would not be able to see timesheet option then how come she is able to see timesheet option.
Release : 15.9.1
Component :
If a Clarity user has "Resource - Enter Time" access right (Allows user to complete and submit timesheets for a resource) and their Home Page is set to "Current Timesheet" they will be able to navigate to Timesheets and submit their time.
