This is the wrong section for this. Try posting in this section: https://community.roku.com/t5/Channel-Issues-Questions/bd-p/channel-issues
Also its possible its an issue with the channel specifically, not Roku. In which case you're better off reaching to ewtn directly, either via their website or social media.
That aside, try removing & re-adding the channel. Also, please elaborate as to what issue you are having, does the video never load and you're taken back to the Roku page, does the channel have all its thumbnails still, does the video play but buffer alot.
