Does nothing but give me a Screen just like Chrome

Wish there was a demo version because I just wasted $4 -there is no inbox screen like they show, it has no ability to essentially change anything from chrome. So what I have is a page that looks just like chrome in a window. Also when clicked new compose got nothing - nada - just a popup which says loading and never changes - Wish I could get a refund and the developer actually represented why this does not work
