Google tests contextual sticker recommendations for the Gboard app
If you want to join the Gboard beta and get access to this feature now, you can Google “Gboard beta” and you should see a page that will allow you to join the beta program. You can leave the beta at any time by repeating the directions above and tapping on the box at the lower right corner that says “Leave The Program.”
If you don’t see an option to “join the beta,” it means that the developer is not offering public beta testing for that particular app. To return to a public or stable version of the app, open the Play Store and tap the profile icon. Go to Manage apps & devices and then Beta.
How do I give the developer feedback about a feature that I am testing?
Tap on the app whose beta program you want to leave to see its detail page and you’ll see a notice that you are a beta tester. Under the “You’re a beta tester” notice, tap on “Leave.” But that isn’t the end. If you want to continue using an app’s public version on Android after leaving the beta, uninstall the app and reinstall it from the Google Play Store.
The point of offering beta tests is for the developer to get feedback from users before a new feature is disseminated to all users of a particular app. So if you do have feedback to share with a developer, once again you open the Play Store and tap on the profile icon followed by Manage apps & devices and then Beta. Tap on the app you want to provide feedback on to see its detail page.
Your comments will not be seen by anyone but the developer.
