Logged in as apple id - Developer account
In the Itunes&appstore section logged out and showing the sandbox account.

It has been 72 hours my app approval. Till now IAP is not activated. Worst service. Terrible experience with paid developer account.
Following steps:
Interrupt service from Sandbox account status off from iTunes connect.
Just login apple id with your sandbox account
The login same as App Store
It’s working fine.
The fact is you already this non-consumable item. And it's never going invalid.
Do you have a solution for this?
I am experiencing the same kinds of problems in Xcode 15.1
