OpenVPN connection issues

[sniffs]

So I have this router, ASUS RT-AC68U. I set up OpenVPN on it, exported the .ovpn profile and imported it into the OpenVPN app on my iPhone. It's an iPhone 7+ running public beta 12.0

OpenVPN connects and will stay connected as long as I'm in the app. The moment I pull the notification bar down, or exit the app the VPN disconnects immediately.

Any ideas why?

Nevermind, I just noticed this thread where they are mentioning it.

Sounds like it's a known issue. Feel free to delete this thread, sorry!!
