View 3D tileset in mobile devices and chrome

1. A concise explanation of the problem you're experiencing.

WE have created a cesium web site with 3D tileset created from ContextCapture.

It can be viewed in I.E11 under PC.

However, I found that the mobile devices, Safari, Microsoft Edge or Chrome cannot view the 3D tileset.

Do you have any idea or advise to us how to make the mobile devices like iOS to view the model.

2. A minimal code example. If you've found a bug, this helps us reproduce and repair it.

Code:

Do the tilesets in https://cesiumjs.org/Cesium/Apps/Sandcastle/?src=3D%20Tiles%20Formats.html&label=3D%20Tiles also not work? In Chrome for example, have you checked the browser’s console for errors?
