Unable to update app from Testflight if Network extension is active.

When we try to update our beta app from Testflight then Testflight gets stuck after downloading the ipa. This behaviour is consistent on iOS 13 while on previous versions of iOS its working fine.I debugged through Charles Proxy and found that download ipa is fine but then there is an API(https://testflight.apple.com/v1/apps/intvalue/intvalue/install/status) request to update status of install, that API is not called here.This update fails whether we intercept the traffic or not.Even whole traffic is going direct even then it fails.
