If you are an employee, please make sure you have an active Revolut Business card and that you log in using the same email address you used when ordering the card.
If you are the account owner or administrator, please make sure that you log in using the same email address you used when you signed up.
Please note that, even if you're the account owner or administrator, if while ordering a new card for yourself you set up an Employee profile not linked with your owner or administrator profile, you'll only be able to see those card details in the mobile app using the same email address that you used while ordering the card, not the one used to log in to the web interface.
