When scheduled sync is enabled, FolderSync will automatically attempt to sync the FolderPair in the background at the time of configured schedules. For each schedule added it is possible to configure custom connection and notification settings, where as before they were general settings applied to all runs.

Battery optimization and other vendor specific "optimizations" are the most common causes for scheduled sync not to run or to freeze without errors. See here for more info on how to keep an app alive in the background if you are facing such issues.
