Its a lot simpler then that. Dont add them to your tailscale account. Each user should have there own tailscale account. Then you just send them a link to share your machine (your server) with their tailnet. Then all of there devices they have added on their account can access your server.
Bonus: send them referrals and you get your device limit increased when they make a account. Which all they have to do is sign in with their google or apple account.
I dont have an apple TV myself yet. But I can tell you one thing. Pretty much all the androids including my google TV Chromecast doesn’t have codec support for the dolby audio like truehd. Its so annoying I can’t play hardly any of the 4k movies I have on Plex. Looks like my options is to ether switch to apple TV, a nivida shield pro, or by a HTPC.
