According to the API - https://developer.garmin.com/downloads/connect-iq/monkey-c/doc/Toybox/WatchUi/BehaviorDelegate.html
onNextPage is supposed to map to KEY_UP but when I test and compile the app between a Physical Button Watch UP button vs a Vivoactive3 (on the simulator) the onNextPage seems like it's mapping to KEY_DOWN.
Is this the supposed behaviour or I am doing something wrong?
