Great but...

I used to be OBSESSED with this app. Then I had to reset my phone and forgot about it. Recently Ive rediscovered this amazing app but I remember being able to shake my phone and changing the theme and now I am unable to do so. My phone works fine with shaking anything else for other apps but I cant change my theme. ): Hoping for an update where I dont have to shake my phone to change the theme. Love it though! ?
