Provide an option to use the old vpn method

I love your app. It does what it says on the tin. Till the last update ruined the fun for me.
I emailed you before but got no answer.
Im currently on a $24 Hexatech vpn subscription which ends on October. I wonder by "compatibility with major VPN providers" you are dropping support for hotspot shield, betternet, Hexatech, and all local vpn providers in my country! Just a few companies use "personal VPN" method".
