I get the HTTP 200 OK success status response code, but nothing happens on the Roku*. Nothing happens to the show on Netflix and it continues playing normally instead of rewinding 10 seconds.
Anyone have any ideas what is happening or ideas on troubleshooting? I have tried Hulu, Prime Video, and Disney+ which supports ECP transport controls, but no luck for Netflix. I assume this means Netflix hasn't implemented ECP support? Netflix voice commands work and I was under the impression that if voice work, ECP should as well.
