Ccleaner does not clean Chrome under Windows 10 pro

Since a few weeks ago CCleaner will not clean Chrome. I have tried all the remedies that I can find and that has resulted in CCleaner running visually in the usual way, but it does not clean History or Download.

Do you have Chrome 'synced'?

If so then it will be restored from the Google servers after you have used CCleaner to remove it from your machine.

CCleaner cannot remove synced data from cloud servers, no 3rd party software can for obvious security reasons.

You can only remove synced data from within the browser itself.
