Question: can external users view my live tv if they have Plex pass? If not, will this be added in the future?

I’ve read that Plex is concerned about poor performance when streaming live tv externally, but I’ve streamed on 4 devices simultaneously outside of my local network on 5g without a hiccup. It probably helps that I have a symmetrical gigabit connection, but that’s beside the point.

No and no.
This is not a question of performance, but first and foremost a legal matter.
