... but it would be better to switch to last / current month!
See video demo - when switching to Week in date selector, it goes back to the previous month (Jan), instead of the current (Feb). Thus, we have to manually fix it by selecting the last (current) month in the date selector first, in order to include those weeks in chart / report! :(
Affected both 3.x and 4.x Matomo branches.
What I suggest is to automatically select last (current) week when we switch to this mode.
