Hi, when I use a single widget, the simulator shows widget correctly. But when I add another widget and group into a WidgetBundle, the simulator can no longer display any widget. It just blank white. On real device, it works fine. Is it a bug of simulator?

Hi, I'm following this article to set my time update in Text field. https://developer.apple.com/documentation/widgetkit/keeping-a-widget-up-to-date I tried to wait for long but my time does not update at all. I'm using XCode 12 beta 2. Is there a bug here? Further more, is there any way to customize the date format? Please support, thanks
