Ok, so when I first up Release, it failed. BUT, I hadn't used DRM there before, and according to about:addons, the widevine CDM was updating the first time I launched Release. After a restart and confirming i have the latest CDM installed, playback works in release now. Can you confirm you're running the latest cdm - about:addons / plugins section and make sure you restart the browser before attempting again. Plugin version should be 4.10.2391.0

Ok, so when I first fired up Release, it failed. BUT, I hadn't used DRM in that install before, and according to about:addons, the widevine CDM was updating the first time I launched. In thast session playback failed. In a second test, after a restart and confirming I had the latest CDM installed, playback works.
