Mobile Sync Log and Mobile Sync Log Clear are available only if a supported mobile device has been set up and enabled in Grades2Go™ (Setup > Mobile Device > Enable).
During every mobile synchronization, the Mobile Sync Log records all file uploads/downloads between Grades2Go™ Desktop and the User's mobile device. Mobile Sync Log Clear erases the contents of the file.
Since this command destroys previous data, it is a good practice to first view the contents of the Log file by selecting Mobile Sync Log. If there's content you'd like to keep, just copy the displayed text to another file for safekeeping.
