I want to ad the streaming service TV Mucho….How can I do that?
It does not appear that TVMucho has a Channel/app developed for the Roku platform. As such, looks like you will have to subscribe/watch from their online site (https://tvmucho.com/) and either cast/mirror it to your Roku device or use an HDMI cable directly to your TV from your phone or laptop.
For the most part. unless development channels, only Channels/apps available in the Roku Channel Store (either on your Roku device or online https://channelstore.roku.com/) are available to install to your Roku device.
