Help & troubleshooting for channels on your Roku device, including adding/removing channels, logging in to, authenticating, or activating a channel, channel-specific playback issues, assistance contacting channel publishers to report issues, and adjusting channel-specific settings.
I would like to add new sling package for my son but they don't allow to add promotional offer on existing account. So I am thinking to start another account on my son's name, but can I watch new channels (from newly added package) on the same Roku device?
I don't know how Sling authenticates, but if you have to sign into each box separately, you should be able to log onto Sling on yours. But you would likely have to log out of your account. I'm certain there's no way to sign into multiple user accounts at the same time.
