Hi there, chad15.
If you haven't yet, please sync the data using an incognito or a different browser. It's to check if it's caused by a browser issue.
I'd would also recommend reaching to the app's support. They'll be able to double-check why you're only seeing old information when syncing data.
Their contact information is listed here: https://apps.intuit.com/app/apps/appdetails?shortName=knowify&locale=en-us.
Visit us again if you have other questions with QuickBooks.
