Hi @yk1,
Thanks for reaching us here in the Roku Community!
We understand you are having an issue authenticating your login with the CBS channel. For channel authentication issues, we recommend contacting your provider directly. It's essential to note that most Roku channels are managed directly by the channel providers themselves. Roku only holds the channels available on the platform.
You can also contact the CBS support team here at contact support.
Let us know if there's anything else we can assist you with.
Regards,
