But what does that mean specifically for users? Does the integration of Amex even work? What restrictions are there and are there better alternatives for Amex customers?

Why doesn’t American Express work reliably with Finanzguru?

Who Mainly used bank accounts, current cards or credit cards from Visa and Mastercard, no problems with Finanzguru – The synchronization works reliably here.

However, who It attaches great importance to integrating its American Express cards into the app.

The lack of API connection through Amex leads to one unstable connection, regular manual safety queries and incomplete data.
