Are you wondering why some of your records are not syncing and after a review found out that most of them are marked as "Inactive"?
First, what is an "Inactive" in MINDBODY Online?
Those are deactivated clients in your MINDBODY Online account so these type of records will be ignored by SyncApps.
If your requirements call for integrating these types of inactive records, then these should be reactivated so that SyncApps will be able to process these record to be synced to your integrated software.
Another workaround is to mass update MINDBODY Online to overcome this limitation to sync to the integrated software initially then the clients can deactivate them later on as needed.
