+3. YouTube does not support programatically toggling the native fullscreen player via it's API. This means on iOS you have two options, neither being perfect:
+
+- Use the fallback/faux fullscreen option which covers the whole viewport (this is the default)
+- Set `playsinline` to `false` and/or `fullscreen.iosNative` to `true` - either option hides the fullscreen toggle in the UI (because of the above API issue) and means iOS will play the video in it's native player.
