I am trying to sign in to two different Amazon apps using two different accounts (my music is on my Amazon account; my books are on my wife's account). On my old Thunderbolt I could do this, and on my wife's Bionic she can do this, but on my Razr Maxx HD, when I sign into an Amazon app, it creates an account under Settings --> Accounts --> Amazon, which it uses for all Amazon apps, thus not allowing me to sign into the cloud player on one account and kindle on another account. I checked my wife's phone, and Amazon is not listed under Settings --> Accounts, despite the fact that she is signed into both the cloud player and the kindle apps. Her phone has OS 4.0.4, whereas mine is 4.1.1. Is this a Jelly Bean thing? Is there anything to be done about it? And yes, I could sign in and out of each app every time I use it, but that's kind of a pain.
