During endless user interviews and tests, this seemed to be a bigger problem than all of the team initially thought. People would almost get angry when we told them that we're putting new (paid) features in their much-beloved banking app. "Why do I need to pay additional fees just to use this part of the app?", was a question they asked a lot. I was puzzled. €0.50 is not a lot of money, and I knew how much effort and months, if not years, it took to create this whole feature. But people kept saying that and it frustrated the team and me a lot.
