Due to Facebook new policies, Pure messenger needs to be reviewed by Facebook to allow it to acces Facebook datas.
This review can take up to 2 weeks.
While awaiting the review, I need you to declare current users as ‘testers’ of Pure messenger to grant you the app access.
Please contact me and give me you facebook user name (not email) or user ID, then I’ll add you as tester.
You can find it in your facebook url : http://www.facebook.com/my_account_name
Thanks for your understanding.
