Redeem codes for business applications are not working anymore in 15.2

When I was in 15.1, redeem codes issued from business apps were working fine. In 15.2 and 15.3, everything acts as if it was working, it says "your app is downloading", but that app it is not downloading. I've attached screenshots. I've looked also into the device logs, and I can't see any errors.

We are facing the same issue since iOS 15.2 is released.

We have the same issues for some ios 15.3 users
