I always thought the messages left by other players in Dark Souls was such a cool mechanic.
They could be helpful, letting the player know to be wary of danger, or they could be completely disingenuous and trick the player into jumping off a cliff and dying.
I always labored over whether or not to take a leap of faith based on other players’ messages cause it was a toss-up whether they were being helpful or trolling, lol.
In my experience, you don’t even need the dedicated Jellyfin client. Just opening it up in a web browser works out of the box, so that’s potentially one less thing to download/install/manage for the clients.
That said, I’ve never tried to access Jellyfin from an iPad/iPhone/Mac so it might not be as seamless as my experiences on Android/Linux based devices. But I imagine they’d be fine; just test it out before you hit the road.
