In InDesign 18.3, there will be software changes that will require an update to Silicon Connector. Due to the nature of the change, you will continue to use your current version of Connector until InDesign is updated to 18.3, at which time you must update to the newer version of Connector.
For more details about obtaining the newest Connector installer, contact your DAM provider.
If you wish to delay the update, you can turn automatic updates off for InDesign using the Manage Auto-updates section of the Creative Cloud application.
