Downloads don't work offline. Disney+ is a great service and we use it all the time. However the main purpose of the app is to use to entertain our 3 year old while travelling. This is fine where we have a wifi signal, but if there is no signal the downloads don't work at all. Much to the disgust of my son having lined up lots of shows for a recent 4 hour flight and after the first episode after takeoff none of which would load.
