hello:
NEVPNConnection -startVPNTunnelWithOptions:andReturnError:
When the app is first called when iOS13 is installed, it will jump to the Settings-General-VPN interface and let the user enter the password. However, after I updated the iOS13 beta version, if the setting APP is off, then the call will only enter the Settings-Common interface, and there is no interface for the user to enter the password. If the setup app stays in the Settings - General or Settings - General - VPN interface, the results are the same as before iOS13.
