Roku in-app Purchasing 006 issue.

Hi guys,

Hope you all help me out. I am creating a roku app with in-channel subscription. I have added a product and it shows approved status.
When I am purchasing by side loading the channel the product is purchased. But when I am published it as a private channel it is giving 006 error code.

1. Why I am getting this ? As my product is approved. On a separate note my account is a test user.
2. My second issue is How roku is going to handle the users.Means is there any need to login or register the users while purchasing.

Suppose a user purchased the monthly subscribed product .Then after 1 month what will be the channel store response. How can a developer check the user purchased and subscription expiration time ?

Please guys I need help . Please give me response asap.
