The app uses its own viewer which shows photos with any logical ordered (no chronological order or by album, totally unsorted, so by showing holidays you will see the end then go back then again the end...) and sometimes videos and photos are shown from up down or laying on the side (and you just cant rotate them, even if in iOS the photos and videos are already displayed correctly). In addition each photo has to load independently, so each time you wanna show another photo you will have to wait a few seconds, but if you let it there to long the TV will stop showing the photo and go back to a TV channel.
