问题
My web application is making use of iFrame to launch a App using custom URL scheme.
With the latest release iOS 9 this has stopped working.
On going through articles online, I have some understanding now that Universal Links are way to go about it or else we can use below hack/code to still launch the app(this results in a alert message asking user to Open/Cancel the call, which doesn't look nice).
window.location = app://
Wanted to check with experienced people here, if there is any other possible way to resolve this as I am reluctant to change the app to support Universal Links for now.
