If you have your own subscription, install and use the standalone Crunchyroll app. Services on The Roku Channel are ONLY accessible by subscribing through The Roku Channel.
The problem with that is that for some weird reason the Roku Channel version apparently has show(s), at least one anyway, that the standalone doesn't. Unfortunately it is one of my favorites too, "Ghost Hunt".(I haven't seen it since they took over Funimation and closed down its streaming service.)
Using the Search from the Roku main menu locates it, both the show and individual episodes, in the "Crunchyroll on RokuChannel" but even going through the entire catalogue of shows in the standalone Crunchyroll, in "A-to-Z" mode so I can be sure not to simply overlook it, fails to have it show up.
