WebGL issues are fixed with Android 6.0. 3D Wayfinder is running again on latest Android.
We discovered WebGL issues with Android Lollipop 5.1.1 version, that was available for Google Nexus devices on August. Now Google has started to roll out Android 6.0 Marshmallow to existing Nexus devices. With 6.0 the WebGL issues seemed to be fixed.
