I have always used plex on my tv, but recently I got the Roku Ultra and I am using the plex software on that. It is a great app and much better than the tv app I had on my LG, however there seems to be something missing, or I am not able to find it, and that is the search option.
On home page you can clearly see the search at the top, and I can search all my stuff, and it works.
However when I switch to my brothers server, there is no search option on the page. I thought hitting star would bring it up, but nothing I can do lets me search a remote server. This function is in my tv software, but not in the Roku software. What am I missing?
