When you go deeper into the menus, you’ll immediately recognize the bright UI theme in line with the material design language, which Google has been pushing for years. The “My apps & games” and also the “Settings” menus are now in white and gone is the green accent color. unfortunately, the previous menu is currently missing the search option in the upper-right corner.
The Account menu also gets re-organized and currently opts for tabs instead of a list. And strangely enough, the Wishlist menu is currently grouped with Notifications and Subscriptions within the slide-out hamburger menu.
The new iteration is 12.6.13 and if you’re still on the older version, try restarting the app. The update is server-side and should show it as soon as possible.
