Strange behavior of vimeo? and --livereload

Hello so my querstion is fast and clear why this part of code works on ionic emulate ios --livereload and why doesn’t without livereload?

  <ion-content class="has-header" overflow-scroll="true" data-tap-disable="true">
  <div id="video" class="row responsive-sm video" >
    <div class="col" >
      <iframe src="{{VideoID}}" height="100%" width="100%" frameborder="0" webkitallowfullscreen mozallowfullscreen allowfullscreen ></iframe>

Impossible to say without controller code / a Codepen.

But you think controller have error? I don’t think so because its working on livereload just without this option it doesn’t work…

I would say, use the Safari Mobile inspector without livereload to see whether your scope variable VideoID is actually changed to a proper URL, and to inspect the resulting DOM from that iframe.
