Currently, the new version of sync with QuickBooks Online is only available to Viewpost.com accounts that initiate the first sync with QuickBooks Online after 6/13/17.
The new version of sync is unavailable for accounts that initiated the first sync to QuickBooks Online prior to 5/04/17. However, accounts will be available to migrate to the new version of QuickBooks Online sync later this summer.
Viewpost will contact you when your account becomes eligible to migrate to the new version of sync.
