Why can't I use a small platinum member I just bought?

Login problems, device binding, payment methods, etc.

1. Login question: Make sure that the gadget has been logged in with the account used when purchasing members.

2. Equipment binding: Members' rights and interests can only be used by binding small members with specific equipment.

3. Payment method: Make sure that the payment method used when purchasing small platinum members is the same as that used on small equipment.
