Make sure the card is active and supports Apple/Google Pay.
Add it to your phone wallet first, then to the watch.
Update your phone, watch, and Revolut app.
Restart both devices.
Check that your phone’s region matches Revolut’s supported countries.
If it still fails, contact Revolut support via the in-app chat — they can help directly.
