Requirements:
First of all, you will need a working VPN configuration & maybe a premium account which you can get from any of these topics:

Next, you will need to install Activator from Ryan Petrich from the BigBoss repo and the app you want to auto VPN .
Tutorial: 1. Make sure you have ticked a VPN configuration so when the VPN turns on, it'll connect to that server.
2. Open Activator settings & select the 'In Application' option.
3. Click more at the top right corner and then tap on 'Application Launch' option then select your app (I'll be using Netflix) & click save then done.
4. Now click on the "Launch App" option and scroll down until you see the VPN option.
5. Tap on the option and then close your settings then open your app.
Done!
Enjoy!
