Family Tree Maker (FTM) is a popular genealogy software that helps users create, manage, and preserve their family history. Its sync feature allows users to link their tree with Ancestry.com and access updates across devices. However, many users face Family Tree Maker sync issues that prevent smooth synchronization between FTM and Ancestry.
In this article, we will explore the reasons behind FTM sync problems and provide simple, step-by-step solutions to fix them.
What Is Sync in Family Tree Maker?
The Sync feature allows users to connect their local Family Tree Maker tree with Ancestry online. With sync:

When sync stops working, users may see messages like:
- “Sync failed — an error occurred”
- “Ancestry not responding”
