These two always return despite adding them to the blacklist:
assets-client.ccleanerbrowser.com locally stored data
onboarding.ccleanerbrowser.com locally stored data
Can you please let us know where you're 'blacklisting' these cookies? Is this in the Cookies and other site date section of CCleaner Browser's settings, or is this somewhere else such as an extension?
Since ccleaner browser is a Chromium based browser, it's in Chrome as well. I have added the above to the "exclusion" list: "settings/cookies?search=cookies" and "Sites that can never use cookies" , It's in the ccleaner browser. I am not using any extensions in ccleaner.
Sorry, I'm having issues with text formatting on your site today.
