Hi all ! I'm a new developer on iOs and I' struggling to get my IAP subscription working in sandbox. I've got it working in debug mode on my test env, where I purposely activate the subscription when in my test backend. So that part works. But now, I want to test in testflight with sandbox user credentials. And I see conflicting instructions. My developer account has accepted the Paid Apps Agreement. I've created a subscription group with localized description in both language my app supports. In that group, I've created 2 products with description, duration, pricing, localized name and description and a review screenshot. At that stage, the subscription is at the state "ready to submit". From what I read, I then need to submit them as part of a version submission to activate the IAP. So I did. But then the app was rejected because IAP don't work. I later found out that I need to attach the IAP to the submission, but I couldn't do it, because the IAP where now in "developer action needed". And even after modifying them to reset the state of the localization, the locale are pending submit, but the subscription is still in developer action needed. So in the end, I re-created 2 new subscriptions (with 2 new product ids). At this point, I see posts and replies in reddit and other places that specifically says that the IAP need to be reviewed and approved by apple to be usable in sandbox. But I also see others that specifically says the opposite, that the IAP only need to be in ready to submit. So which is it ? If I submit again the app, I'll end up with subscriptions that are unusable that I can't get back to ready to submit without sending them for review. Thanks for any hints !
