Webview issues with iOS

I am trying to embed a Youtube video via Webview on the app. There a javascript wrapper that we created to get some events from the embedded video (like no of secs watched). This is working fine in Android, but the entire widget does not load in iOS. Is this a know issue?

@adminyi7yav have you considered working with the YouTube API to do something like this?

So, I am trying to show a youtube video in my app, but its not allowing full screen mode. I used a webviewer and gave the youtube embed link with iframe. Something like this -

<iframe width="748" height="421" src="https://www.youtube.com/embed/PtqS0siIeKY" frameborder="0" allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe>
