App freezes and buffers a lot with slow internet speeds. Hulu and Disney plus handle slow internet much better than Discovery plus. Also, when casting from a phone to a smart TV, the app crashes every commercial break, loses show progress, and forces you rewatch the same ads when trying to manually skip ahead to where it crashed! Funny how it remembers to play the ad, but loses show progress! The work around is to not use your smartphone for anything else while casting...a stupid app design.
