Note：

1. COS custom policies are counted toward the total number of custom policies created by a root account. If you see a prompt saying that The number of custom policies exceeds the upper limit (1,500), but the number of CAM custom policies has not reached the upper limit, you can go to the bucket list in the COS Console, click a bucket name and enter the permission management page to check the number of access control lists (ACLs). The combined total might have reached the upper limit.
2. COS custom policies are counted toward the total number of policies directly associated with a user, user group, or role. If you see a prompt saying Failed to associate the policy, but the number of associated CAM policies has not reached the upper limit, you can go to the bucket list in the COS Console, click a bucket name and enter the permission management page to check the number of access control lists (ACLs). The combined total might have reached the upper limit.
