Our app create a GroupActivity with a fallbackURL points to our website ( the url has included the conentId to played).
Exceptal behavior is when a Watch Together invitation is issued by an iPhone user to a user on a Mac, Safari will be launched and asked to load the URL that we provide in GroupActivity. Actual result is Safari launched but URL not loaded.
What should the fallbackURL be? Or what should we do any other things except set fallbackURL?
