I have a Galaxy Tab S7 and for a trip to Spain I downloaded some stuff to watch on the flight. When I got on the plane none of the stuff downloaded on Disney+ would play. Maybe an issue with downloading to the SD card? I don’t know, but regardless Disney offers SD card as a download destination so they should make sure it is working.
So now I’m here pirating a show that should be available to me through a service I pay for. Gabe was right, piracy is a service problem.
Get VLC Media Player or another similar of choice. Where it’s easy for you to manage & watch/ listen to any media of choice.
Enjoy your upcoming travels.
