The "People" feature of the Google Photos app started disappearing for some users earlier this month, numerous posts on Google Product Forums reveal. The tab that previously allowed users to quickly locate photos featuring certain individuals recently went missing for some users both in and outside of the United States, and the Mountain View-based tech giant already confirmed it didn't remove the functionality. Instead, the feature seemingly went missing as a result of some unspecified bug and Google's team is currently investigating the issue with the intent of fixing it as quickly as possible, as revealed by one of the company's community managers. There's still no word on how long the issue will take to be resolved, though a Google representative promised users will be notified as soon as the firm's developers have an update on the situation or manage to fix the problem.
According to several online posts and limited testing, the People tab didn't disappear on a global level, but it's currently unclear how many users are affected by the issue that apparently only started manifesting itself several days ago, while the feature itself has been introduced in early April. In light of that fact, it's possible that the problem was created by a later server-side update to the app, though it's more likely that the new software build that hit the Google Play Store on Friday is the actual culprit responsible for the ordeal.
In case you're running the latest version of the app and can't see the People section, make sure you've previously enabled the "Face grouping" functionality in the Settings menu of Google Photos that's accessible by tapping the hamburger menu in the top-left corner of the main interface. If that option is enabled and the People tab still isn't showing up, there's not much you can do but wait for Google to resolve the issue, which will hopefully happen sooner rather than later. In case you've just disabled the "Face grouping" feature by accident, the contents of your People tab were permanently deleted and the app will once again have to build all face models and labels before it starts populating that section once again.
