App Store Review Team has just rejected my binary (Verification failed, cannot connect to the Apple ID server)

[zoftify]

Version of react-native-iap

4.4.6

Version of react-native

0.61.5

Platforms you faced the error (IOS or Android or both?)

iOS

Expected behavior

App Store Review Team is able to verify IAP purchases

Actual behavior

App Store Review Team is facing issue connecting to the Apple ID Server:
In fact, this popup is a system one, so I don't really understand why they aren't able to connect to the Apple ID server. Our in-house devices work just fine.

Tested environment (Emulator? Real Device?)

iPhone running iOS 13.4.1 on Wi-Fi.

Any help is much appreciated. Thanks!

The issue happens while requesting a purchase. I've just tried to create a brand new sandbox account and I faced exactly the same issue, but with a production account, it works like a charm (yeah, when the app is downloaded from TestFlight). Do we mess things up or something to be fixed in a library?
Thanks!
