How disable catalog syncing

[Bazsl]

I am trying to help a fried who has two catalogs, one for testing and his main catalog. When he launches LR he gets a message stating that the test catalog is being sync'd and if he would like to have his main catalog sync'd all the photos in the test catalog will be merged into the main catalog. He does not understand what caused LR to started syncing the test catalog. He does not want either catalog sync'd to the cloud (or anywhere else). He has paused syncing. How can he turn off syncing for the test catalog? Thanks.

In both catalogs- Click the Cloud icon and [Pause Syncing]

Cloud "Syncing" does NOT combine or merge two Lr-Classic catalogs! For that the function to "Import from another Catalog..." is used.

Thanks Rob. If I understand you correctly, pausing syncing is the correct way to prevent a catalog from being sync'd.

Yes.

And be aware, if syncing,  that setting a Lr-Classic catalog to sync only syncs proxy (smart Previews) to the Lr Cloud, and only photos that have been added to a Standard Collection that is marked to 'Sync'.
