Button Doesn't Launch App Until I click elsewhere

I created a button to launch the Sonos app on one of my Roomie devices (iPhone 4s). I then synced it with Dropbox to the other devices (iPhone 5 and iPad Mini). On these two devices when I click the Sonos button it will not launch the app until I try to do something else in Roomie (click another button, click on the Room itself). Does anyone else have this issue?

Thanks.
