Just switched from chromcast to Roku stick

OMG it's like night and day. I have an older LG smart tv, 2015 and got tired of waiting for them to release the app for older lg's. So I took the leap and bought a roku stick. I've been using the free chromcast they sent me.

Wow..no more casting from my phone. Way more channel options than even my tv apps offered. I'm hooked. Questions though, I added FXNOW and Amc, AMC automatically recognized I had youtube tv and was in like flyn, FXNOW though didnt, it asked if I had an account, I tried my YYTV account name, nope. Theres no option to select tv provider, the app on my phone recognizes and logged me in thru yttv a while ago. Don't wanna set up a new account unless that will give me the same access I have thru yttv. Also any word when we will be able to log into the the turner channels. Thanks. New Roku Convert
