In App Billing does not load google page

Dear, greetings.

In a recent community search, I didn’t find any topics that would help my problem.

I appreciate the attention of anyone who can help me.

I have done many tests and I was not successful.

The point is that clicking “Make a Subscription” nothing happens.

I am using the blocks below.

Can someone tell me where I’m going wrong?

Thank you very much.

When “BT_Sobre” is clicked, “Long Click OK” is displayed, then “Permission Granted OK” is displayed, but nothing happens.

I created these blocks to control and see what was being returned.

Result obtained from app already published on google play
