reachability - Network-change notification doesn't work as expected using SCNetworkReachabilitySetCallback on iOS

Question

I am testing cronet to obtain HTTP rtt，building my APP with Xcode 12.3,

cronet adds a callback to receive notification when network changed, code details here;

but I cannot get notification at some cases when I turn off the network or turn on the network,

and sometimes get a wrong network status, eg. I turn on the network, and get a notification of

CONNECTION_NONE rather the right answer like CONNECTION_WIFI.
