Disclose Transaction Fees

Can the Curve app disclose the fees that have been incurred with each transaction?

All my other bank and credit cards do this (I guess it’s compulsory for them, not sure why Curve isn’t covered by it?) whereas Curve seems to only adjust the FX rate used on foreign transaction fees.

Some of my overseas purchases have a 0% fee, but others cost 3.5% and it’s not possible to work out what fee has been charged. Would be useful to know how much I’ve paid, and when I would have been better off using a cheaper card like my American Express.

I’ve never used my Curve in an ATM - do the fees get shown nicely in the app for these sort of transactions? If so, can you re-use the functionality to itemise and disclose the foreign transaction fees please?
