Braintree iOS Webview issues focusing inputs inside iframes

Ionic Framework ionic-v3
1

Hello,
I’m trying to integrate Braintree hosted fields solution in my app, but I’m facing issues on iOS devices

When I tap over an input, which is inside an iframe, it throws a blur event almost instantly.
In a very few cases the focus is maintained and I can write on it.

Any clue?

What’s the difference between iOS app and Ionic View in terms of Webview engine?
I just tried in Ionic View and its working perfectly

Should be none, except if you are using WKWebView in your app or did something else to it by using some plugin.
