Of onSelect, onNextPage, onPreviousPage and onMenu functions that should be called when the corresponding button is pressed, only the onSelect is being called

Hi, a user with a Forerunner 945 and another one with a MARQ Expedition device has said that the Prev and Next buttons not being sent to the widget anymore (they cycle between the widgets). I sent them a debug version and sure enough, onPreviousPage and onNextPage are not being hit. I can't duplicate it in the Simulator as it works fine there. Are there some reasons why it would behave that way now? The view delegate is extending the BehaviorDelegate class. I have :

onHold,

onTap,

onSwipe,

onSelect,

onNextPage,

onPreviousPage,

onMenu,

onBack

defined in that delegate class.
