I read the reply to the question about discovery+, but I am still confused. Why do these have different content? We paid for an ad-free subscription to discovery+, have watched for several months and then suddenly the program we have been watching (The Repair Shop) is no longer available, but is available on the discovery+ on Roku Channel. I don't get this. I'm paying for discovery+ why can't I get the content that is available directly on discovery+? I shouldn't have to have 2 subscriptions to the same streaming service.
