I've run into some issues using an app called StrongSync, which uses the FileProvider API to mount various cloud services. The mounted folder was showing stale results and missing content. In attempting to troubleshoot, I uninstalled and reinstalled, deleted and recreated the connection multiple times, but it simply does not appear in Finder, and a folder does linger in ~/Library/CloudStorage even with no folders configured. The company that authors the software has been unresponsive.
Is there a command or API call to remove/reset that folder in CloudStorage?
