To find out if your card is verified:
Tap on the "cards" tab at the bottom
You should see your card at the top. If the card's email isn't verified yet, you will see a message underneath the card with a "verify your email" button.
Tap the "verify your email" button and follow the prompts
If the message is not there, it means your card has been successfully verified.
PS. If you recently verified your card and it still shows as 'unverified' - try closing and then re-opening the app again. It sometimes can take a moment to reflect in the app.
