[Back](./) # Why is the Zoho Project sync in progress for a long time? The initial synchronization process may take some time, as each module is fetched individually. Until the sync is completed for all modules, the **Instant Sync** button will be replaced by a **Refresh** button. Clicking the **Refresh** button, lets you check the status of the sync. You can also verify if the integration was recently disabled or if the **ZSC key** was regenerated , as these situations may also result in a longer sync duration than usual. If the sync has been in progress for more than two hours, write to us at [support@zohobooks.com](mailto:support@zohobooks.com) for further assistance. * * *
