Please be noted that we do not have a dedicated Roku presence in Puerto Rico at this time, so it is very likely the channel is not currently available on the Roku platform.
Channel availability/access on Roku devices will vary from region to region. A Roku device will work in any location, however, channels may not be available on your device in that location, based on each channel provider's discretion. For more information, you'd want to contact any specific channel/service provider to inquire further about whether they offer their channel/service on the Roku platform in your region.
If you have any other questions or concerns, please let us know.
