Cookiebot offers full support of the required 'prior consent' so that only strictly necessary cookies are set on the user's browser before the user consents.
If you are using automated cookie blocking and you find that cookies are being set before prior consent have been obtained, please make sure that at least 24 hours has passed since you signed up. Cookiebot needs to first complete a scan of your website and analyze your cookies before being able to block all of them correctly. This first scan may take up to 24 hours.
If you are using manual cookie blocking mode and you experience that other than strictly necessary cookies are set before the user has consented, you need to implement prior consent on your website.
