Why Do I Still See "RDS Extended Support Enabled" After Upgrading MySQL version?

I was about to create a Post when it found yours.

It's happening to me too -- on two accounts containing both MySQL and Aurora Postgres. I think there is something bigger going on.

What I was going to write:

I'm coming up on 24 hours since I upgraded, and RDS Extended Support is still on two separate accounts. Both MySQL and Aurora Postgres instances. Documentation says it ends the day of the upgrade. FWIW: When I remediated MySQL in our main management account, it unenrolled immediately.

Hello.

If the upgrade is successful, I think it will be automatically canceled.

You can end enrollment in RDS Extended Support at any time. To end enrollment, upgrade each enrolled engine to a newer engine version that's still under RDS standard support. The end of RDS Extended Support enrollment will be effective the day that you complete an upgrade to a newer engine version that's still under RDS standard support.

By the way, "RDS Extended Support" displayed on the "Configuration" tab of the RDS instance is displayed because it is now possible to opt out, as described in the document below.
So, there is actually no need to pay any additional fees if the version is 8.x or higher.

UPDATE For everyone who is seeing RDS Extended Support on. I still think this is overly confusing, but oh well.

Here is what the RDS team got back to my Billing case:

As described in the user guide below: >>> https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/extended-support-overview.html You can end enrollment in RDS Extended Support at any time. To end enrollment, upgrade each enrolled engine to a newer engine version that's still under Aurora standard support. The end of RDS Extended Support enrollment will be effective the day that you complete an upgrade to a newer engine version that's still under Aurora standard support.

The fact that “RDS Extended Support” column is displayed as “yes” on the management console does not indicate that RDS Extended Support is being charged. When creating a new version 16.2 Aurora PostgreSQL cluster, “RDS Extended Support” column is displayed as “Yes” when created with “Enable RDS Extended Support” enabled. Of course, this cluster isn't currently eligible for Extended Support charges.

When creating a new version 16.2 Aurora PostgreSQL cluster, if “Enable RDS Extended Support” column is disabled and created, “RDS Extended Support” is displayed as “No”.

**The yes/no display in “RDS Extended Support” column shows "EngineLifecycleSupport" field in the output of describe-db-clusters. **

“RDS Extended Support” column's value is displayed as “Yes” when “EngineLifeCycleSupport” field is “open-source-rds-extended-support” value, and “No” is displayed when “open-source-rds-extended-support-disabled” value. T

**The “EngineLifeCycleSupport” value can only be set when creating a cluster or restoring from a snapshot. It does not indicate that Customer are eligible for RDS Extended Support charges. **

Note: By default, this value is set to open-source-rds-extended-support , which enrolls your DB cluster into Amazon RDS Extended Support. At the end of standard support, you can avoid charges for Extended Support by setting the value to open-source-rds-extended-support-disabled . In this case, creating the DB cluster will fail if the DB major version is past its end of standard support date.

You can use this setting to enroll your DB cluster into Amazon RDS Extended Support. With RDS Extended Support, you can run the selected major engine version on your DB cluster past the end of standard support for that engine version.

**Additionally, I would like to inform you that the charges for all the mentioned accounts has been stopped from June 8th, 2024. **

I then observed here and confirmed that my RDS costs dropped off daily:
