Hi @Thomkat910,
Welcome to the Roku Community!
For more information about that channel's subscription policy and functionality, you'll want to contact the channel's customer support team to inquire further. Many channels on Roku are developed and maintained by the channel provider themselves.
You can reach them here: ALLBLK Support
Please let us know if there's anything else we can help you with.
All the best,
Chel
