Your app doesn’t have any in-app products yet

Hey Team,

Thunkable Pro user would like to earn some of this money back by charging a monthly subscription (both platforms) for a published app. I have not seen this issue resolved anywhere.

Google Play requires In App Billing and reports:

Your app doesn’t have any in-app products yet.
To add in-app products, you need to add the BILLING permission to your APK.
Upload a new APK

Has this been resolved anywhere? Does the classic extension still work?

Thank you.
