Browser settings to view course through AOL on a mobile phone

Hi

I've read the following tutorial to understand how to set the player features in order to see a course through Articulate Online on a mobile phone (Nokia Lumia)

http://community.articulate.com/tutorials/products/changing-the-browser-settings-and-player-size-in-articulate-presenter.aspx

I've tried various possibilities but it's not working. The browser window remains too big for the size of the mobile display.

Do I have to change the presentation size in ppt?

Thanks
