Please fix this app

I am using this app to keep up with Starz shows, as I have a subscription to the channel. But this app always has problems. When I am trying to download a show to watch, it closes and restarts the download several times. It can take over 30 minutes to download a show. Also the shows have started not playing back when downloaded, so that if I want to watch a show, I have to stream it, which defeats the purpose of downloading it. I want to enjoy this app, please fix!
