There seems to be a bug with the Stamp Card.

Hello EA Support,

I completed all 6 Daily Challenges today in the World's Club event. However, my Stamp Card only shows 6 out of 7 stamps, and I didn't receive the 7th stamp or the reward.

I have already restarted the game, but the problem is still there.

Could you please check my account and help fix this issue?

Thank you.
