Under certain circumstances, it may take a while for the myPWS Apple Watch app to get settings from the myPWS iOS app transmitted by iOS and activate them. Usually it helps to start the myPWS Apple Watch app, keep it in the foreground, make settings in the myPWS iOS app and confirm them with the 'Done' button. The myPWS Apple Watch app should then adopt the settings within a short time and after a data refresh.
