I have been waiting for the OS 7.5 update for my Express+ because of the screen mirroring feature. Yesterday I tried updating and it did, so now I have OS 7.5.1.
But for some reason, I cannot find the screen mirroring feature.
I want to cast a Chrome tab to Roku, so to experiment I downloaded a Chrome extension, but if I try to use that I get "No cast destinations".
Is there anything else I need to do to make screen mirroring work?
