@Shanmonster@lilithsaintcrow BUT—you knew there was a "but" coming, right?—you have to disable enhanced visual search on EVERY Apple device linked to your iCloud account separately. I checked and disabling it on my main Mac, or my main iPad and iPhone, didn't disable it on my laptop or my other iPad …
Every. Single. Device. Rather than a common setting (hint: the Photos library is synced across devices, why aren't the settings?)
@Shanmonster Quote: “To turn off, go to Settings > Apps > Photos on iOS and turn off Enhanced Visual Search. On Mac, open Photos and go to Settings > General to do the same. You must do it on each of your Apple devices.”
@Shanmonster@lilithsaintcrow On macOS, the setting is buried in the settings within the Photos app. On iOS/iPadOS all app configuration is managed via the Settings application (under "Applications->Photos").
