P2 signed up for the card and met the spending requirements. Points from the spending already posted to the Marriott account, but couldn’t find the certificates anywhere when signed in to Marriott website. Where should I look for them?

Edit: They showed up when I signed out and signed in under Activity.

Same situation: Cat 4-6 properties requiring 50K points can be booked with certificates, but Cat 7 properties requiring 50K points can be booked with points only.
