Hi,

The drone visualized by the 3-axis in the 3D map view goes away intermittently. However the dot in 2D can be still clearly seen and moving. If I restart voxl-portal, I can again see the drone in 3D. Any idea how to fix it?

On the related note, where are the html files of the portal located in the docker/voxl board? Suppose I want to change the color etc., which html/css files should I change? 

Many thanks. Warm regards,
Arjun
