Vertex Color information not recognized

I’m facing an extremely weird issue with vertex color , my mesh is vertex painted, it works fine on my side.
However, after committing the map to source control , the vertex color does not appear on my other teammate’s computer, in their version of the map which is exactly same as mine , the vertex color is completely white ( visualizing with vertex color in ‘Show’)

I suspect something is causing the vertex colors to be not recognized. This is extremely weird because I can safely delete my map and refresh from repo and the vertex color would appear.
