Has someone of you had an FX payment recently? I had a USD payment from my EUR account on Feb 1 and they charged a lot more than 0.5% network fee.
Support figured out that they used the rate from the day before, not the one from the day the payment was made on. They can’t fix it because MasterCard supplied them this old rate they say.
You might want to check your FX rates. Would be good to know whether this is a more systemic issue or just a one-time fluke.
Still disappointed by the answer 🙁
