iOS Question help with subscriptions

[fastlingo]

It's the first time I am developing an ios app and my first experience with appstore. I want to implement a monthly subscription in my app
I tried the code here:

Verify receipts for "Auto-renewable subscriptions"

For a current project, it was necessary to verify "Auto-renewable subscription" purchases in the Apple App Store. Since the available information on this was very extensive and often confusing, below is the variant that works for me. Maybe it saves others a time-consuming odyssey through...

I get a red line in the logs saying: Product not found: all_access_one_month
it seems to come after this line

istore.RequestProductsInformation(ProdIds)

I have a single subscription in the app (all_access_one_month) and it is selected in the screen with the app build where it says 'Add for review'

I do not understand if I have to send the app for review before testing subscriptions or if there are other requirements. What am I missing? The information about this is confusing to say the least, although in app purchases is a crucial aspect of development.

Start with a non-subscription product based on: https://www.b4x.com/android/forum/threads/istore-in-app-purchases.49301/#content

I made a in app purchase (non consumable) named premium

Dim l As List
    l.Initialize
    l.Add("premium")
    store.RequestProductsInformation(l)

But I get the same response when I start the app with b4i bridge : Product not found: premium
I don't know what i am doing wrong. The app is not reviewed yet.

My problem is that the products are not even recognized with store.RequestProductsInformation, I made the products in app

Does the app have to be reviewed first and add in app purchases later?

It doesn't need to be reviewed. Have you created a test account?

 

[fastlingo]

Yes, I realized I have to use a sandbox account, I created it, I logged out of my apple account on the iphone, I went to settings->apple account and I logged in with the sandbox account. Still get the same message: product not found when I use store.RequestProductsInformation.
Now I am in the process of completing all the legal forms with apple (trader contact information etc) thinking that might be the problem.
