I'm bumping this string https://community.roku.com/t5/Accounts-Billing-Orders/Removing-channels-online/td-p/413428 because I believe you should be able to remove channels from the channel store.
Yes, you should definitely be able to remove channels from time Roku website.
I just need to know how to remove Starz. I cant seam to use it so would like to stop paying for it.
