I have been traveling to Iceland and recently also made a purchase in CZK.
I see an initial amount debited and then the transaction record just vanishes. I exported a statement to check, and it always shows Up as:
Original debit -22,34 czk
Refund +22,34czk
New debit -22,42 czk
I don’t mind the FX rates being balanced but at least show the transaction in the transaction history
