Why does the wrong animation play when I press the AR button?

[kanthiganesh]

I am trying to animate model in ar mode but only the first animation of the model is playing.
Browser:Chrome
OS : Android
this is my code.
<model-viewer id="artag" alt="A 3D model of an astronaut." src="RobotExpressive.glb" animation-name="Walking" autoplay ar>

Hi, if you launch AR with the ar attribute, you are using Scene Viewer (which is a native Android app). Currently, <model-viewer> allows you to configure the playing animation, but Scene Viewer only supports playing the first animation in your model.
