Nope its defo a change thats rolling out as my Xbox starting looking like it a week ago, 2 of my users reported the same around the same time and last nights server update (Beta client) changed my web interface so this is defo new.
How it looked
How it looks now
And if I change this to Manage manually I can get the old not so cluttered view back however i can ONLY do this for the web interface not on my Devices where I actually watch Plex witch is what is so infuriating
