Won't stop buffering – Sundance Now: Series & Films Review

I've been trying to watch The Staircase for 3 days but it keeps freezing or buffering (I am Chromecasting) and there is nothing wrong with my internet or router or connection. All my other streaming apps work perfectly fine when Chromecasting so this has to be a problem with the app! Very disappointing...I'll never finish The Staircase now ?
