My app is made but I need specific subscriptions in terms of months. 1, 3, 6, and yearly: all at different rates in Canadian currency. It must also include the ability to pay by debit or visa Mastercard and the rest. I could not even figure out if I have to incorporate the subscription blocks into my app or upload it separately on Google Developers. My app was uploaded but when it came to subscription nothing happened.
You might use this latest in-app billing extension ↓
Payment method not what I need.
It is somehow unclear what you want
The built in billing component is outdated and therefore does not work anymore…
You have to use one of the billing extensions, for example the extension by @JEWEL
To find alternatives do a search in the community or the extensions directory App Inventor Extensions | Pura Vida Apps

Thanks for your response 
I am unclear on how subscriptions work. Does it have to be added to my app or does it have to be uploaded separately? I am looking to make monthly, quarterly, and yearly subscriptions. Help me please. $$
for a working solution you have to add a billing extension into your project
