Is it safe?

Enrollment takes place on official Google pages, and the app installs from Google Play. This portal does not ask for passwords, verification codes or personal details.

This is a test version: it may contain bugs and some features may change.

Does Google say you do not have access?

Check that the group and Google Play use the same account. Finish joining the group, then reopen the beta link. If the store page says “Not found”, complete steps 1 and 2 with that account first. Access may take time to update. If it still does not work, contact support.
