The Google Play Store is simplifying how you can opt-out of beta programs, pre-registrations for apps and games, as well as clear out your Wishlist. There is a new "Google Play preferences" section in the Play Store's settings that will allow you to do what we mentioned above with just a tap of your finger. In this part, you'll discover one-tap options for clearing your Wishlist, leaving all beta programs, unregistering from upcoming events, and removing all app or game pre-registrations. However, the feature is not showing up to all users at this time.
Before this option showed up, you could manage features like these on a per-app basis. The Wishlist is accessible in the side menu, while the beta programs are in the My Apps > Beta section. But now you can sort of Thanos snap these out of your life. Aside from making things simpler, this move could also help with troubleshooting. Beta apps can include more software bugs, so this might be a clean and easier way to get those out of your phone.
