From my android app I do a login with Login With Amazon, using a user amazon account. Then I want to logout and login again using a different account. But even if I call signOut on the AuthorizationManager and cancel all tokens, when I call again the AuthorizationManager authorize function, I get authorization code without a new login screen. To get a new login screen I have to open Chrome, navigate to the Amazon web site and logout the user from the Amazon site. So how to logout the user from the Amazon site too so that a complete new login screen is shown when I request new authorization?
