About Enrollment Status

I bought iOS Developer Program and I get mail (Your order is being processed).

But in member center I see that message

• Enrollment Status:
• 1. Submit
• 2. Identity Verification
• 3. Accept License Agreement
• 4. Purchase and Activate

Purchase and Activate Your Membership

You still need to purchase and activate your membership to join an Apple Developer Program. Purchase Now

1, 2, 3 checked - 4 not checked.

I don't understand why.
