Sync settings from previous version *still fails* with DW 19.0!

Dreamweaver 19.0 does not import previous settings from 18.2 which have been saved to the cloud. I agreed on opening to update from the cloud which it didn't do. Then I went to sync settings > manage and checked "Import sync settings" and restarted Dreamweaver. Under Sync settings it said updated settings are available, so I updated, and still nothing happened.

I then uninstalled, including preferences, and reinstalled, just in case I missed something, and went through the whole process again! Still exactly the same.

This is just frustrating and broken, just as it was in the last version. Why can't it just update from local settings like the other CC apps? Is there any way I can do this manually? Copy files over from App Data? I don't want to waste my time painstakingly remembering and setting prefs, workspaces, shortcuts, snippets from scratch! Come on Adobe!
