Wont cast

About a week ago,APP quit casting to chromecast. Also giving other errors. Shows will play on phone and iPad but my daughter uses the app to cast to our tv. Disney tech support is aware of the problem. However not sure if they are trying to fix it or not. DISNEY, PLEASE UPDATE AND FIX APP.
