Alexa Skill
Not really a TV app but closest category I could find, I think an Alexa Video Skill would be great for twitch as I would love to be able to watch streams on my Echo Show, seems strange that this isn't already a thing considering that Twitch is owned by Amazon lol, obv would then be able to utilise features such as connected Echo devices for surround sound as well as the 3D Sound and Subwoofer products they also sell for this ecosystem

Twitch skill is a myth, maybe existed few years ago but nothing shows on my alexa skills search. I just want to log in twitch on echo show so I don't watch ads.

This already exists, it's the "Twitch" skill. I use it all the time, and came here to complain about how it handles ads :)
