Parental controls for R6900v2

Today, I upgraded my Nighthawk R6900v2 firmware to V1.2.0.92_1.0.1

1. The R6900v2 documentation dated Feb 2022 says I should be able to use parental controls

2. When I click on parental controls in my updated NetGear genie, it says my firmware does not support Live Parental Controls, and says the following:

Checking router firmware

We're making sure you have firmware that supports Live Parental Controls.

Your router's current firmware does not support Live Parental Controls. Please go to http://www.netgear.com/ to download the latest firmware or use the "Router "Upgrade" feature in your routers web GUI at http://www.routerlogin.net/ to update the firmware first.

3. This webpage says the R6900v2 is not supported for Circle Smart parental controls

4. This URL says:

NOTE: The Live Parental Controls service is no longer supported on NETGEAR devices as of December 31, 2021 due to low usage. Support for Live Parental Controls has been removed from the NETGEAR genie app and from updated firmware versions. NETGEAR Smart Parental Controls is the replacement for the Live Parental Controls service. For more information, see Support for Live Parental Controls ends April 1, 2021.

So, even though the User manual for the R6900v2 says I should be able to use parental controls, all the available documentation says this model does not have currently have support.

Is there any other 3rd party way to set this up, or am I stuck with no parental controls vs having to purchase a new unit?

Thanks in advance.
