App confirmation works 1 out of 5 times. The notification doesn't show. No way to force a confirmation from the app. No way to re ask confirmation. Private and business card on the same app, no thanks. Using it with a shared business card is a nightmare. The only thing working is the transaction history. Edit 2024: it's worst. It almost never works. Always crash and notifications doesn't work.

Most of the time the app is actually working, sometimes it's just in limbo and I cannot access my derails at all. That leaves me with a rather uncomfortable feeling since I don't know if someone else could access my account during that time. Also not being able to export the transaction data for analysis purposes is really poor. Currently I need to manually take and type the data from the analysis function into an excel spreadsheet which is ineffective.

App suddenly denied access to aleady set up account. Neither fingerprint, password nor password reset worked. Then I used it for applying for a new credit card and it just didn't and didn't send the verification code to my mobile at the very end of the credit card application process. Please, if your systems don't work and can't even make sure an SMS gets sent, please make sure that happens at the beginning and not at the end when everything has already been entered.
