I mentioned this problem once before a year or so ago but it's happening again. Shows that are WWE shows do not show up the next day after they air? Sometimes it is 2 days sometime it is 3 or more days. NXT is now behind by 2 days why does this keep happening?
What/when content is available in the WWE Network channel would be outside of Roku's control.
You may want to consider contact WWE Network support directly:
How are you watching WWE in the first place? Hulu? The WWE Network channel? Either way it has nothing to do with Roku. When the network release them they do. So can you provide some more information please
