I had a couple of transactions that were labeled as ‘food and drinks’ by bunq, but didn’t generate cashback because the transactions are labeled as something else by Mastercard (merchant code). This is confusing and is not transparent for the user.

so the following idea:
Shouldn’t you make the merchant codes avalaible in the bunq app, or pair the bunq classification to the merchant codes. I reckon this is going to be an issue when you release the cashback feature to a broader audience.
