I've been watching the Sister Wives series for several weeks. Was in the beginning of Season 12 when the episodes all "locked" (have a red key on them) and tell me they're only available if I have the TLC channel, which I do through DirecTV
Thanks for the information.
For more information about that channel's features and functionality, you'll want to contact TLC Go support directly to inquire further. Many channels on Roku are developed and maintained by the channel provider themselves.
