Bug: Can't enable Memory — Reference chat history disappears

I’m trying to enable the new Memory feature in ChatGPT settings, but when I toggle “Reference saved memories,” the “Reference chat history” option disappears completely, and the memory never actually turns on.

I’ve tried refreshing and using different browsers. Still no luck. Attached is a screenshot for reference.
![The image shows a settings menu with options for data controls, builder profile, connected apps, security, and subscription, alongside customization and memory settings.

Has anyone else encountered this? Is this a known issue?

Toggle under the “Learn more” and you will see.
