I strongly suspect it’ll be the Curve card triggering Airtime Rewards, not the underlying one.
Unless I’ve completely misunderstood how all the ‘on card’ schemes work - my understanding is that it’s all based on the PAN (card number) used at the time of transaction. Hence Google/Apple/Samsung Pay breaking it (since they present a different PAN).
I’ve had my first transaction tracked. I think it showed a day after so it’s definitely working.
Not so. My purchases on my RBS card are always done through Google Pay as I have never carried the card. All have tracked.

I am on iOS 15.5
