Google Play Console - can't create subscriptions even tough closed testing App was uploaded

Question

I can't create subscriptions in Google Play Console. It says "Your app doesn't have any subscriptions yet" and there is only the button "Upload new APK" whih leads to closed testing.

But I already did that and it was approved! What the hell does Google still want??

Answer 1

You need to upload an APK with implemented Billing Library into closed testing, after review you can create subscriptions. Don't forget to add a test user
