would like to add vpn configurations not working

Hello,


On iOS beta 13, I have installed my existing VPN application, and testing the regular behavior.

When user tries to make a connection it requires the allow permission,


"*** Would like to Add Vpn Configurations"

All network activity on this ipad may be filtered or monitored when using VPN.

Allow Dont Allow


After clicks the allow permission it takes to the Settings page and suppose to prompt for the password,


But here in iOS beta 13, it takes to the settings page and prompts nothing, and it just stays like that. Its absolutely unexpected behaviour.
