If Sparkk TV is not showing up in the channel store on your Roku, it means that your Roku is not compatiable with our app. Make sure your model is 2014 or newer and running the latest software. After upgrading to the latest software, try looking for our app again in the channel store. Feel free to Contact Us using the Contact Form if you are still having problems. Be sure to include the software version, Roku model and any other information we can use to make sure we can solve your problem.
