Netflix and Hulu won't stream stream on AppleTV 4k

One of my two AppleTV 4k devices have stopped being able to stream Netflix and Hulu programming at all. The other experiences periodic issues. It is fine on my older, non-4k device. Streaming is fine on other apps such as ABC, NBC, FOX, CW, AMC, etc. It feels like the "play stream" trigger/functionality is failing. I have restored them to default, all software is up to date. You can load the show listings and navigate without issue, however when you attempt to watch something, you get a spinning red image in Netflix that freezes after a few seconds and it's a silver/gray spinner in Hulu that freezes after a few seconds. Hitting Menu takes you back and you can once again navigate. However, there is no way to stream from either 4k device. I have tried via WiFi and ethernet. Same issue. Connected to 300/30mbps connection, so there is plenty of bandwidth to stream (and it works for all others). Again, this only affects Netflix and Hulu. I found another post about this, but it was locked and required creation of this new thread. Anyone have a solution yet?
