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.
Can you please clarify the issue you are experiencing? How are you subscribed to those channels? Are you subscribing through the channel provider directly or through Roku Pay?
If you already have an active subscription to those channels, when accessing them on your Roku TV, you shouldn't need to "activate" those channels, but rather simply authenticate your account information.
With more information we will be able to assist you further.
