Testers reporting they can't install your app? These are the most common reasons your opt-in link fails — and exactly how to fix each one.
1. Country Restrictions
Did you limit availability to specific countries? Our testers are global. Action: Go to Production/Testing track → Countries → Add all countries.
2. Review Pending
Is your change still "In Review"? Users cannot download the app until the track status is "Active".
3. Email List Not Updated
Did you press Save after adding the Google Group email? Double-check the email address for typos.
4. Cache Issues
Sometimes the Play Store link takes a few hours to propagate. Ask testers to clear their Play Store cache or try the web link.
