Hi Experts, My app contains a system extension(VPN network extension), but it somehow can not be launched after multiple activations(via OSSystemExtensionRequest activationRequestForExtension) without deactivation. I just found my extension can be restarted automatically if I kill nesessionmanager in such case, so 2 questions: it's a system bug or misuse API that my system extension can not restart after several activations by activationRequestForExtension without deactivation first? is there any official way to restart nesessionmanger instead of killing it?
