iOS In App Purchase - "Invalid Product ID" in release, NOT development version

Question

I created a new app and uploaded the binary to iTunes Connect, then tested IAP using the test user account, both on the simulator and on the device. Both worked.

I submitted the final app and it is currently live on the App Store. However, after deleting the development version from my device and downloading my app from the App Store to test IAP, the app immediately receives an "Invalid Product ID:" error.

Once again, the development version worked using the test user account, but live on the store it does not work and returns invalid product ID. Any ideas what this might be? If anyone wants to test this (in case it's just me) the app is called "ContaX" and is free with ads - you don't need to actually buy the upgrade, just see if it crashes after tapping the remove ads option.

Answer 1

I advise you to wait for 24 hours after your app is approved.

Sometimes it takes more time for the in app purchases to be available in the released application.
