Funktioniert nicht nach Update 3.32.0

Absurde Empfehlungen durch Administratoren/Entwickler, zudem äußerst widersprüchliche Argumentation. Ein Schelm, wer Böses dabei denkt…und sich nach diesem Kommunikationsdebakel auch noch mit dem Kundenservice auseinandersetzen muss, oder mit dem hilflosen KI Chat…. Komplett daneben, volle Punktzahl Note 5 und der Entwickler wird sich bedanken :-))
Kunden falsch informiert: Korrektur erfolgte erst am Sonntag 10.5 gegen 8h.

Response from developer

Danke für dein Feedback. Wende dich bitte unter 022855005500 an unseren Kundenservice.

Complex

Hard to set up difficult to use and when I finally get in the system is often updating or telling me PB is on strike. Not great

Good idea

Overall an important security mechanism. The QR activation code scanning is flaky and locked up my installation. Had to wipe and try a 2nd time.

Response from developer

Sorry that the activation via QR code did not work for you. It is important that you have the latest version of the app on the second device. Only then can you send the QR code on it and scan it with the other device.

Horrible interface, not intuitive

I’m an old man. I had to invite a person to help me to understand how this system works.

Funktioniert nicht mehr.

Die App macht seit einigen Wochen nur noch Probleme. Man kann sich anmelden, so oft wie man will aber nichts führt aufs Konto um die Kontobewegungen zu überwachen oder Überweisungen zu tätigen. Leider hat auch das letzte Update nichts gebracht. Leider kann man nur einmal pro Woche, wenn überhaupt aufs Konto zugreifen, dann schnell versuchen die Überweisungen zu tätigen und dann gibt es schon wieder nur Probleme. Echt zum Abgewöhnen!!!

Who is this app intended for?

This app is ideal for individuals who prefer to manage their online banking primarily through a computer and require a separate, secure method for authorizing transactions, rather than integrating it into a full banking app.
