Julian I would like to try this out with my German bank accounts. Seems like you have been a bunqer for quite some time now, and you were already able to get a sub-account with German IBAN. Did you just create a new sub-account through the regular flow in the app?
Edit: Ansonsten denke ich, dass Bernds Aussage zutrifft. Es dauert sicherlich einige Wochen, bis alle Institute in Europa die deutsche BIC von bunq entsprechend für Echtzeitzahlungen freigeschaltet haben.
