continuity

My devices: iPad Mini (latest), iOS 8 dp5. Macbook Air, Yosemite dp5. I have Handoff working between the two above devices. Safari, Mail, Messages, Calendar, etc. all handoff with no problems. I can even handoff between my website on the Air and my native app on the iPad. What I can't do yet is go from my native app on the iPad to my website in Safari on my Air. For the first view controller that loads in my native app, I have this: - (void)viewDidLoad { [super viewDidLoad]; NSUserActivity *webHandoff = [[NSUserActivity alloc] initWithActivityType:@"com.myApp.iphone.staging.webbrowsing"];
