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 just activated a 2nd Roku player today. After doing so, I purchased a subscription to Blaze TV. I did this through the new player. I then added the channel on the first player, but it wont let me log in or use the channel
For more information about that channel's authentication and functionality, you'll want to contact Blaze TV support directly to inquire further. Many channels on Roku are developed and maintained by the channel provider themselves.
