What do the expense statuses mean: Synced / Syncing / Failed?

The sync status appears as a label on the expense details screen and shows how well the expense data is synced between the mobile app and the system. The three possible statuses are:

• Synced: the expense data has been successfully synced with the system, and no further action is required.
• Syncing: the expense is currently being synced with the system, and the process hasn’t been completed yet.
• Failed: the expense data failed to sync with the system.
