Follow their instructions, restart YouTube and boom no ads.
A few things to note;
They limit your speed at first, their service is free cuz they sell ur data
They offer a “premium” speed ($30), don’t buy it, you can get it free.
To get it free you need another device, you simply use the referral link on your phone and send it to the second device. Download the app and turn on the vpn. Delete the app and repeat the process till you have “premium” speed.
If you already use a vpn this app will conflict with it as it works like a vpn but doesn’t hide location.
