Thank you for reaching out on the community and telling us about your issue. With mobile sync it syncs the selected accounts all the way back May 1st, 2017. It's still a bit further back but not all of the way. In case you're wondering how to set it up as well here's an article that should help guide you through the setup.https://www.quicken.com/support/how-set-and-sync-accounts-quicken-mobileweb
