Hi, @Villegas
Greetings, and welcome to the Roku Community.
We appreciate your inquiry regarding the availability of channels on Roku. Kindly be advised that channels on Roku are managed by the channel providers. Channels might have set a limit on the availability of their channels on Roku. You can still stream these channels by screen mirroring them from a device to your Roku. For more information regarding this, kindly visit this support article at How to use screen mirroring with your Android™ or Windows.
We hope this answers your inquiry.
All the best,
Kash
