It's been a long time since the Google Play Store received a major UI update. The last major UI update came in 2019 when the app received a redesign in the Material Theme. Since then, except for a few minor tweaks, the app has stuck with the same design. However, Google is now releasing a new UI that gives the Play Store a big facelift.
The most striking change is the removal of the "hamburger" menu. This is part of Google's renewed focus on getting rid of navigation drawers, as they tend to conflict with full-screen navigation gestures. We've already seen Google remove the "hamburger" menu in Google Photos and Google Maps, and the Play Store is the last to get rid of it.
Going to other changes, you will notice that everything has been moved to the profile section in the upper right corner. If you have multiple accounts, they are now hidden under a drop-down menu. Below the account tab, we see things that were once under the "hamburger" menu. The library replaces the Wishlist, and Payments and subscriptions are now together. Applications, games, Play Protect, Notification and offers and settings remain the same. Some users also see Play Pass and Play Points listed next to these options, but they were missing on our device.
Finally, the settings receive a refresh. All options and preferences are divided into four folding categories. Earlier all this was on a huge list.
Google has been testing this change for some time, and as part of this test, some users already have this redesign available on their devices. However, Google is finally releasing this UI to all users.
The new UI is widely available to Android users. If you still do not see it, try clearing the cache and closing the Play Store application. You can do this by going to Device Settings or by holding down the Play Store app icon and clicking on the app settings. You should see a new one UI when you reopen the application.
