title: ion is not a known element - angular language service
body: <p>I created an app in ionic but the angular language service returns this error:</p>
  <p><a href="https://i.stack.imgur.com/nk4Iy.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/nk4Iy.png" alt="enter image description here" /></a></p>
  <p>So my question is simply do I have to disable this extension or is something wrong?</p>
