Subscription billing

Hi there

I am gonna change my app to monthly subscription.
Have searched and found:

App Inventor Extensions: Billing | Pura Vida Apps 22

The questions I have is:

  1. Does the blocks go on my first screen, when my app starts?

2)Do I have to make a subscription platform/screen or will Play store have theirs? I must just have the blocks?

Thank you in advance

It sounds like this would be a good idea

The billing extension already has everything you need

You might want to test the example projects...
