Hi, I was wondering if anyone knows a way to get Secure-line vpn to work on the Nvidia shield. I managed to place the Apk on the Shield. It looks like a cell phone version. I log into avast . It says I have a multi use license and when I think it will work a box pops up asking for a voucher. Not sure if Avast has a specific version for Nvidia Shield. This is my first time using a vpn or the Nvidia Shield. So sorry if this is a noob question or posted in the wrong place. Thanks for any help. 
Thank You
