If you have correctly followed step 4 of our manual implementation guide when you implemented Cookiebot or if you are using automatic cookie blocking as described in our standard implementation guide, then you should be fine. Just make sure that if your scan report shows any new cookies, then these should also be marked up the same way you have done with the other cookies and trackers on your website.
Some Cookiebot users may have deliberately chosen not to implement 'prior consent' before 25 May 2018 and only show the cookie information to their users. Then, now would be a good time to complete the implementation.
If you would like to read more about 'prior consent', how to implement 'prior consent' (with links to various installation guides) and a tip for how to check if it has been correctly implemented, please see What does ‘prior consent’ mean and how do I implement it?
