Funktioniert nicht!

Standardmeldung ist „Verifizierungscode-Fehler“. Die kommt immer, egal ob ich den richtigen Code für den richtigen User eingebe oder irgendwas anderes. Ergebnis: Kein Login bei „Synology Photos“ möglich, katastrophal!
Abgesehen davon ist die Einrichtung auf einem neuen Gerät eine volle Katastrophe. Es ist vollkommen unklar, wo der zu scannende QR Code zu finden ist. Irgendwann finde ich ihn dann doch, aber warum kann man das nicht vernünftig dokumentieren?
