On the second screen where you have a big green "PLAY" button, there is a check box marked Auto-play. If you click this whilst the loading is still on-going, you do not need to click the PLAY button - which can only be clicked after the loading has finished.
But, you have to do this every time you login. The Auto-play button should be persistant, that is to say, you should click it on and it should remain on for all sunsequernt logins until you click it off again.
It's not as if there isn't time to click it off again whilst loading if you don't want it on at a later date.
