I have an Android app on Google play store with alpha and beta testers (in addition to production) and so far everything was working well. I am trying to add a new user to the closed beta testing list on google play store. This user is already using the app on production. For some reason, although his email address is in the beta testing list, he cannot see and download the version that is published to beta. (Only the version on production). Any reason for that or a way to fix this?
Edit: I continue to experience this problem: Once a user have already downloaded the app on production, he cannot become a beta tester. Does that make sense?
