So danke an das Dev Team, nun gibt es die Version 1.23.1 als Beta Release. Hat es damit schon jemand getestet?
Der TOKEN Button funktioniert nun, auch ohne PIN 
ABER, einen Token bekomme ich leider nicht zurück... läuft auf Fehler. Kann es bitte mal jemand anders versuchen, ob ich mich irgendwie doof anstelle?!
