Current behavior: Built an ionic app. Running the app on android and iphone real devices. Android works perfectly. iPhone I can't select any dates and the disabled days look the same as the selectable days.

Expected behavior: I expect iPhone and Android to be pretty much the same. I expect to be able to select dates on iPhone.

Steps to reproduce: Run the app on an iPhone. The same code works correctly on Android but not on iPhone.

openCalendar() {
    console.log('openCalendar()');
    let today = new Date();
    let startDate = new Date().setMonth(today.getMonth() - 1);
    let endDate = new Date().setMonth(today.getMonth() + 1);

    const options: CalendarModalOptions = {
      title: 'Select Dates',
      pickMode: 'multi',
      canBackwardsSelected: true,
      defaultDateRange: { from: startDate, to: endDate },
      defaultDates: this.dates,
      to: new Date()
    };
    let myCalendar = this.modalController.create(CalendarModal, {
      options: options
    });

    myCalendar.present();

    myCalendar.onDidDismiss((dates: Array<CalendarResult>, type: string) => {
      console.log('Dates back from modal: ', dates);   });
  }
