gltf from blender - no animation for scale

[le-horge]

Hi folks,
I´m relative new to ventuz and I´ve tried to begin with a simple scene import: a cube that rotates and scale ... (as gltf) ... the Windows-Gltf-Viewer shows the animation corrrrect - in ventuz there is only the rotation to see. No scale. Any suggests?
Thanks
