I did what u said. I check and tick all country but not solved

I found the solution at the end of three days.

Every subscription was only active for Germany, and we kept getting this error when a device registered in the UK downloaded it from the app store.

If you can't solve it despite all instructions, make sure to check this situation as well.

make sure all countries are available.

Here are the logs when trying to fetch the products and display the paywall:

Kindly share the verbose logs of recreating the issue. The articles here contain the instructions for all platforms: https://docs.adapty.io/docs/configuring-adapty-sdk

I have checked all 1-5 of the steps multiple times and am still unable to resolve. Are there any other reasons that this error would occur? After days of work I am going to have to switch to react-native-iap

Hi there! Please follow steps from this article to fix the issue:
https://docs.adapty.io/docs/testing-purchases-ios#error-1000-noproductidsfound-no-in-app-purchase-product-identifiers-were-found

Error 1000 (noProductIDsFound): No In-App Purchase product identifiers were found
If you are encountering this error, please follow the steps below to resolve it:

Check if all the products have been added to Adapty Dashboard.

Ensure that the Bundle ID of your app matches the one from the Apple Connect.

Verify that the product identifiers from the app stores match with the ones you have added to the Dashboard. Please note that the identifiers should not contain Bundle ID, unless it is already included in the store.

Confirm that the app paid status is active in your Apple tax settings. Ensure that your tax information is up-to-date and your certificates are valid.

Check if a bank account is attached to the app, so it can be eligible for monetization.

Also, ensure that your products are in “Ready to Submit” state.

Let us know if that helps!
