Hello,
This is a reminder to update your policies to avoid changes to your access to AWS Billing, Cost Management and Account consoles. Our records indicate that you are still using retired actions to access these consoles.
If your policies are not updated with new actions by December 11, 2023, your users’ access to the AWS billing, Cost Management, and Account consoles will be affected.
The policies that need to be updated to include the new fine-grained actions are listed in the “Affected Resources” tab of the AWS Health Dashboard in the “Policy | Policy Name | Policy ARN | Type” format.
To help you with the migration, we have published a mapping between old and new actions in our user guide [1]. If you need to update policies across multiple member accounts in your organization, we have built bulk policy migration scripts to help you update all policies quickly and securely from your management account. See the bulk policy migration scripts user guide [2] for more information. You can find a detailed guide on how and which policies you need to update on our blog [3] and definitions of new IAM actions in Cost Management [4] and Billing [5] user guides.
AWS will not be able to grant further exceptions after December 11, 2023, so we strongly recommend that you act promptly to migrate your policies to new actions.
If you have more questions or need help make updates to your policies, please contact AWS Support [6].
Sincerely, Amazon Web Services

Not only did they send me this email, they sent me 10 copies - one for each account we have. Pages and pages of documentation, steps to follow, Cloud Formation stacks to create, Python scripts to run, etc. I'm still not completely sure what the problem was or what is supposedly improved, or if I would've actually lost access to anything, but hopefully the emails stop now.
