Home page differences depending on Browsers

I have encountered a frustrating situation in that the Zoom Home Page appears differently depending on the browser used. I personally use FireFox in Windows, however, some of our users use Chrome or even a different OS (Mac) . Those that do are presented with a different home page that does not look the same as the one in Firefox nor does it have the same options. Why? How can i document how to setup and host a meeting if the process is different depending on browser type? Is there a way to ensure that all see the same thing when they go to www.zoom.com?
