Hello,now I've updated my version from Android AG Auth 3.1.0 to 3.1.1 and it stopped working. If I revert back it works again, but at 3.1.1 it returns this stackTrace:07-06 06:40:33.690 5751-5751/com.kumuluz.ccm.android.sample D/KeycloakHelper: Keycloak failure: AuthorizationException{error= invalid_request} 07-06 06:40:33.690 5751-5751/com.kumuluz.ccm.android.sample W/System.err: AuthorizationException{error= invalid_request} 07-06 06:40:33.690 5751-5751/com.kumuluz.ccm.android.sample W/System.err: at org.jboss.aerogear.android. authorization.oauth2.
