[SOLVED?] InAppPurchase ID not found - what am I doing wrong?

Hi,

I have an IAP class, which is fully working on iOS.

Now for Android I set up a Managed Product in my Play Console and released the app to the Alpha Track.
The managed product has the same identical identifier as it does on the AppStore.
(com.company.app.iapName)

But on Android the InAppPurchases::productsInfoReturned() callback comes back with an empty products Array. It never finds my one single purchase, even though I pass the correct identifier to InAppPurchases::getProductsInformation().

What am I missing? Do i need to put it in beta first?
I have also waited for over 24h between creating the Managed Product and trying to find it in my app

//EDIT:
Apparently waiting a total of 2 days did the trick and I can find the purchase now all of a sudden…
