I had submitted one of my windows phone 8.1 app on the windows phone store and marked it as beta release.. I had provided the couple of testers microsoft emails as test users(couple of emails separated with semicolon) and submitted the app.. The app was approved and when i try to install on my device using the tester microsoft account, then it shows the error message like "You don't have permissions to install the app".
Below is the screen shot of beta selection of the app and emails provided. Please let me know if i am missing anything like any permissions to be given to testers in beat release of the app.
Thanks Kalyan
