Bug
ChatGPT Web shows contradictory Personalization state depending on how the same settings page is opened.
Reproduction
- On ChatGPT Web, click the user/profile menu → Personalization.
- This view shows Enable customization = OFF, and the Custom instructions field is empty/disabled.
- Close it.
- Open user/profile → Settings → Personalization.
- In this view, my saved Custom Instructions are present.
- Open the ChatGPT macOS app → Settings → Personalization.
- The same saved Custom Instructions are also present there.
Actual behavior
The same account simultaneously shows:
- Web → Profile → Personalization: customization OFF / Custom Instructions empty.
- Web → Settings → Personalization: Custom Instructions populated.
- macOS app → Settings → Personalization: Custom Instructions populated.
The Custom Instructions also continue to be applied in actual conversations, despite the first Web view showing customization as disabled.
Expected behavior
All Personalization surfaces for the same account should reflect the same persisted state.
Impact
This can make users believe their Custom Instructions were disabled or lost and may cause them to change a setting that is actually still active.
Screenshots attached showing all three states.
