When on my local network, the Plex app is painfully slow\unusable. Every other device on the network works fine. I have 4 rokus and a Chromecast (this lags because the app is lagging). Please check this video out, it shows exactly what I'm getting at.
My router is a Netgear Nighthawk. I feel it's probably NOT the router. Server is connecting just fine to the outside world.
I'd love some feedback\assistance as the app inside the house has become useless and I use it to control my Rokus pretty regularly.
