I pay for this service and cannot use it. I called tech support and the representative was very kind and patient and professional. We troubleshot detailed steps, including making sure the app was current, my TV system was current, and removing the app and re-downloading, restarting the TV, and doing an IP address and speed test... but in the end I was told that my internet connection may be too fast for Disney's servers to function with my TV. Yup, internet is TOO fast for 4k app streaming.
