Select the More tab and from there look for a line item called Settings or Login. Follow the login instructions. Once you are logged in, the app will sync your personal items such as scheduled sessions, stars, and notes. When you log into the app from another device, your personal selections will be downloaded on that device and will remain in sync with other devices.
Internet access is required for synchronizing your data across devices and backing up your personal selections. If WiFi is slow, it may take a few minutes to sync the content. Check back after a few minutes and try visiting the schedule view to see if the data has been received.
