In App Purchase Sand box Testing

I have implemented in-App purchases in my existing App, In-App Purchase Product Status: Ready To Submit

All banking and tax-related information is set in App Store Connect.

it is more than 24 hours, I am Facing the Error:

#  Purchase of this item is not currently available
This item is being modified. Please try again later.
[Environment: Sandbox ]

Thank you

Accepted Answer

I also got this error when trying using sandbox

For new app, this error happen too. I'v tested on my production apps and they are all still work, Just new IAP items not work.

This will cause the submit for new app or updates got reject for sure.

How was it fixed? @otnielhez
