As a foreigner working in China, I need VPN for every aspect of my life and work to access all the things I use for my daily life and work (and most are blocked here, specially Google).
Twin Apps feature seems to create a separate storage in system level to have clone apps run. However, as this storage works independently and doesn't support any VPN app, so all those apps I add as twins don't work at all. It's not even possible to add a separate Google account for twin apps as Google is blocked here...
You should let user add some VPN apps to this storage otherwise it's totally useless.
