We are building a game using the Corona Gamesparks plugin.

I built a login screen using username/password + facebook sso auth. All works great except when doing gamesparks requests - after suspending/resuming or restarting the app - I get "error":{"authentication":"NOTAUTHORIZED"}.

Do I have to manually re-authenticate when the app re-launches? I read that the auth token doesn't expire, so I thought that the plugin would handle this automatically.

Also if the user switches account, do I need to tell gamesparks to sign out (and how?)... or is it enough just to sign in with another account?

Thanks, Jacob 

Adding this call after initializing gamesparks seems to fix the problem:

gs.setAuthToken(authToken)

I would still like to know: if the user switches account, do I need to tell gamesparks to sign out (and how?)... or is it enough just to sign in with another account?
