Cool... point me to the LG TV tailscale app.. or the roku tailscale app...
SDNs in general are no different. App support is limited, specifically on devices that people are most likely to want to watch media content on.
And to say that tailscale is "that's it" is a bit disingenuous. On my setup (LXC containers) I couldn't add tailscale even if I wanted without faffing with interface stuff.
