Hi all, New to Plex but all was simple. Yesterday I installed Plex Server on my Macbook and purchased the Plex app for my 2 Android devices. For 2 hours or more I had my Apple TV 3 in my cast menu on all 3 devices, it cast flawlessly, even H265 files which my Apple TV wouldn't usually play, which is why I tested Plex and a great many other apps over the weekend.
As titled it just vanished, from everything. I have reinstalled Plex server on my Mac, restarted all devices including the router, I'm logged in on all devices. Overnight it hasn't returned. What's going on? Frustrating to say the least as this is an extremely good solution, the only solution to cast H265 files to Apple TV 3.
