The G Suite Data sync setup is available in Automation features. Choose the preferred option from the dropdown menu. We highly recommend to use the Add/remove Users option by default.
If you’re not sure about what possibility to choose, check the detailed article about their differences.
Now click Set and it’s all done!
Be careful about one option available in this menu: OFF (manual synchronization only). Make sure you don't have this one picked if you want to utilize the synchronization.
Use this option only if you wish to "pause" the synchronization. That may come handy when you work on structural changes in G Suite and you don't want to sync it until it is ready.
Daily G Suite Data Sync is an important prerequisite if you wish to automate setting up signatures to new (or moved) users for Credits or include new users to Subscription.
