I recently found out about the latest Google testing services. This is Closed Beta testing and Open Beta testing at this link: https://support.google.com/googleplay/android-developer/answer/3131213 and http://readwrite.com/2015/07/30/google-beta- test-tools .
To try the open beta feature, I did the following:
New Beta APK Uploaded
Set email id for feedback
Set the maximum number of testers.
get the Opt-in URL (after that I canβt find a single save button or anything, as indicated in the documentation.
Distribute this Opt-in URL to testers.
The following is the problem I am facing:
When I click on the select URL through my Android device, it first asks me to log in. But since I'm testing Open beta, which is not limited to a specific set of e-mail messages (gmails), as well as any Google+ group or any Google community, why does it take me to the Google login page?
After logging in through my personal inbox, I get the following error message: 
Has anyone encountered such a problem before? Am I something wrong here?
Any information regarding the same should be really useful for anyone who wants to try the new beta testing service.
Thanks in advance.
