T'was leaking my ipv6 address until I turned off the ""Bypass VPN for local networks"" setting. This has been the best OpenVPN client I've tried so far for Android. A lot of the others I've tried  especially the proprietary ones  had often random disconnects with little to no attempt to reconnect  regardless of what settings I tried playing with. -Tested on a Nexus 5X
