Change that formula to:
Set(currentUser, User());
Set(weeksList,
With({_startDate: DateAdd(Today(), Weekday(Today(), MondayZero) * -1, Days)},
ForAll(Sequence(20, 0),
With({_weekStart: DateAdd(_startDate, 7 * Value, Days)},
{StartDate: _weekStart,
EndDate: DateAdd(_weekStart, 6, Days)
}
)
)
)
)
(There is no need for the concurrent function - it will yield nothing to this formula)
Change your Dropdown Items property to:
ForAll(weeksList,
{Value: Text(StartDate, ShortDate) & " to " & Text(EndDate, ShortDate)}
)
This should give you what you are looking for.
