Logging in with Android

[CursedRider]

Hey there, I am a noob on SW and want to play it in Android.
I created an online account, downloaded the app in Google Play. Started the app, it required connection to the drive - granted.
Launched the first tutorial, and after the victory it required me to enter the username, but rejected my already existing username because, well, it is already existing. Did not manage to find any option in the beginning to enter manually username and password. It just forced me into the second battle... Please help, thanks

The solution I found was going on with the second tutorial, then in menu registering a different address for the game, and only then change accounts...
