Removing a member of a Google Play Beta Test

The user will need to leave the test. They do this by going to the link that you originally provided (i.e the link that they used to enter the test) and clicking "Leave the Test."

The closest thing I could do was to close the Beta track for my app. This is the Remove Testers button inside the manage beta page. I still don't see a way to remove individuals from the beta test.

While logged-in to the Google account that you'd like to leave the BETA program, hit the following URL (replacing "your.package.name" with your APK's package name)

https://play.google.com/apps/testing/your.package.name/leave

You can also send the BETA tester this link.
