One of the following settings must be selected: “Accept cookies” will accept all cookies; “Accept cookies only from visited website” will reject third party cookies sent from domains other than the one currently visited; “Do not accept cookies” will reject all cookies. See https://help.opera.com/de/latest/web-preferences/#cookies.
The user is again informed that by returning to the home page and starting navigation, they automatically give their consent to accept the cookies. In the absence of a specific choice made, the website settings are made so that cookies are sent by default. Finally, we remind you that the non-acceptance of third party cookies may result in not being able to use all the functions of the website. Unfortunately, we are not able to list the consequences of not accepting each cookie individually, as we are not able to infer the consequences of all possible combinations of accepted or rejected cookies.
