The only caveat with this is that we found the app/TVs by the elevators to be instantly updated if shows were cancelled/added vs. relying on a printed schedule that could become outdated pretty quickly.
We had some issues with the app because it is SUPER RAM intense, but realized if you closed a bunch of apps it would work fine. Once we figured that out, if we had any issues it was usually because Facebook/instagram was open in the background. Swiping those closed allowed the app to work. Not ideal, but worked for us!
