Hello, i want to order this device but i have one question. Can i install Plex on this and stream it from a remote plex server from a friend?
There is a plex app for Roku.
Just depends if there is a network path from your device over the internet to theirs (no issues if on same domestic router).
Try first with a laptop or mobile phone.
Plex stinks on Roku. I have a cheaper fire stick that works but my Roku Ultra won’t play Plex trailers. Makes me angry as I have to switch back to fire stick and get all the Amazon pushed content.
