We have an under-development app which we uploaded to TestFlight for testing.And recently we tried to implement Universal Links and wanna test whether it works on devices.So we download app from TestFlight and opened web link in safari browser.What we got is that after retreiving the apple-app-site-association file we put under server root,instead of launching test app, app store was launched and "content not available" showed up.Does that mean before releasing our app to App Store, we have no ways to test Universal Links function?If anyone could give us information on this, it would be a great help.BTW, we have gone throught programming guide below,https://developer.apple.com/library/prerelease/ios/documentation/General/Conceptual/AppSearch/UniversalLinks.htmlbut no related details could be found.
