Google Earth Tour does not open balloon on Google Earth iOS / Android App

[GoogleCodeExporter]

I'm creating Google Earth Tours with KML. They work just fine on the Desktop 
version of Google Earth. However, on the iOS Google Earth App or the Android 
Google Earth App the balloons do not open when approached.

Here is a link to an example KML. Just press Play Me in Google Earth to play 
the tour. In iOS/Android, it should start automatically. A balloon should open 
when the animation stops near the numbered icons.

I use the following KML to popup the balloons:

<gx:AnimatedUpdate>
  <Update>
    <targetHref/>
    <Change>
      <Placemark targetId="115111546534262.03">
        <gx:balloonVisibility>1</gx:balloonVisibility>
      </Placemark>
    </Change>
  </Update>
</gx:AnimatedUpdate>
<gx:Wait>
  <gx:duration>2.0</gx:duration>
</gx:Wait>
<gx:AnimatedUpdate>
  <Update>
    <targetHref/>
    <Change>
      <Placemark targetId="115111546534262.03">
        <gx:balloonVisibility>0</gx:balloonVisibility>
      </Placemark>
    </Change>
  </Update>
</gx:AnimatedUpdate>
Thanks,

This happens with the latest versions of Google Earth App on iOS 5.1.1 on iPad 
and Android 2.3.5.

Nick,
