Getting Component exception: TypeError: undefined is not an object (evaluating '_this.scroller.scrollToDate') when updateWeekView is called

Hi,

My calenderstrip component is as beow:

Upon getting focus on the screen, I am using the ref and calling updateWeekView as below:
useFocusEffect(
React.useCallback(() => {
if (calComp.current) {
calComp.current.updateWeekView(moment().weekday(0));
}

}, []),
);

But, if I comment this out and load the page and uncomment the updateWeekView call and navigate back to the same page, it wont throw this exception.
