If you have tracked time against a work item or contact in Karbon but it is not showing in QuickBooks Time, it is likely that the work item or contact is no longer connected and/or the code in QuickBooks Time has been deleted.
In this case, we suggest following these steps.
Save & Sync the connection between QuickBooks Time and Karbon from Settings > Connected Apps > QuickBooks Time. This will resync the connection between the two apps and prompt Karbon to re-check for all QuickBooks Time codes.
From then, if anyone attempts to track time against a work item or contact that is no longer linked to QuickBooks Time, the following message will appear.
3. If you see this message, a new code can then be created, which will re-link the item to QuickBooks Time and allow time to be tracked.
