The Plays tab on the mobile app will show any plays from the FastScout Web Plays tab that you have sent to mobile while the Playbooks tab will show any playbooks. When you navigate to the Plays tab on the mobile app, you can then filter the plays by Season, Team, or Series.
Once you click into a play, you can scroll through each frame. If you have attached video to the play, it will show up after the frames. You have the option to "Play All" videos as well as download the videos. You can find the download button in the upper right corner of the video.
