I am trying to add in-app purchases to my app. I created a StoreKit Configuration file and checked the option 'Sync this file with an app in App Store Connect' because I have already completed the subscription setup in my Apple Developer account.
I also tried implementing the in-app purchases directly without using the StoreKit Configuration file, but I’m getting an 'Invalid Product Identifiers' error. I’ve double-checked, and the product ID matches the one listed in my Apple account.
Please guide me on what I should do.
