The solution of “​<Error>: Could not successfully update network info during initialization.”

What happened

The error message like below happened on iOS when launching an app and crash immediately.

​<Error>: Could not successfully update network info during initialization.

Before this message happened, I purchased a lot of auto-renewal subscriptions, about 300 times, and restore over and over again for testing purchasing subscriptions.

The solution

Restore your device to factory settings. For me, the error solved by it.
