In the Clarity mobile app, when going to the My Timesheets section, a period shown appears as "Open" (Current Period, Next Period or Previous Period), but the period is closed.
Clarity Mobile App 3.3.4
The items shown in the My Timesheets screen are timesheets corresponding to the current, next or previous periods (but not periods). The status refers to the timesheet status for those periods, not the period status.
