Reproduce e.g.: new email -> select "Empfangsbestätigung (MDN)"
The blue siwtches e.g. "Empfangsbestätigung (MDN)" or "Übermittlungsbestätigung (DSN)" imply that they need to be draged to one side rather than beeing pushed in order to "switch" them:
Actual result: Draging them (like a physical switch) does not work. One has to "push" them like a button.
expected result: Siwtches should work via both actions: pushing and switching!
