@dlynch Thanks for the note here. Could you please provide more information about what you are trying to sign in to on your Roku device?
Roku doesn't limit your ability to sign into your account, our channel, or The Roku Channel as you described, so I'm not quite sure what you are referring to.
If you are trying to access a specific channel or service on the Roku platform, and are seeing an error message, you'd want to contact that specific channel/service's support to report the issue and request additional help and information.
Please feel free to provide more details about what you are referring to, and we'd be happy to continue assisting however possible.
Thanks,
Tanner
