I'm using this app and it's really well made and works well even with my set top box. I noticed that there's an OpenVPN client built in and this would be really nice for my stb because it would be much quicker to use it instead of browsing for the VPN app and then selecting the iptv app every time. However, I followed the few guides I found online but it doesn't work. I'm adding my .ovpn file with the server configuration, then writing my VPN service username and password, but I don't have a way to put in my .crt,.key and .pem files which are of course needed to establish an OpenVPN connection. Has anyone managed to use it properly?
