What is the Roku Express model number? Settings > System > About
I noticed that there have been many instances over the years of Now TV not working with Roku Express, listed both on the Roku forums and the Now TV forums. Depending on the model number, some app developers do not support all the different Roku Express models. The developers pick the ones they support, and your model number may help determine that.
Also, everything I've seen from Now TV shows a Stick, not an Express in the images. It may be that a Stick or better is required for Now TV in your region. Let us know your model number and we can go from there.
