The updated footer no longer includes a direct link to the 'Do not Sell or Share My Personal Data' page. Previously, this link provided quick access to California Consumer Privacy Act (CCPA) opt-out controls from the footer menu. Users can likely still access these controls through the main Privacy Policy page or dedicated privacy settings, but the removal eliminates a prominent, footer-based navigation shortcut. You should verify whether this opt-out functionality remains accessible through other menu locations or settings.
