Banners are shown again only depending on the configuration done by user in their Admin Interface from the Appearance tab
What happens if auto-update is selected?
In that case, if the Data Processing Service is marked for auto-update, it still depends on the selection: Which kind of update has been triggered by the auto-update and which options (major / minor / patch) have you selected in the Admin Interface?
If I change the settings for major/minor/patch updates, will this affect visitors who already have seen my CMP?
Yes. For example, the admin goes to the Admin Interface, selects major update. The visitor goes to the website and gives their consent. Since it is configured to the show banner on each major update, the visitor will see it again if a major update happens.
Later, the admin de-selects major update in their Admin Interface (i.e. the banner should no longer be displayed, even after a major update). The visitor would see this change after 30 minutes from when he visited the page. That means, 30 minutes after he visited the page, he will have the new information that he should not be shown the banner anymore.
The information about the CMP setup is stored in the visitor’s cache for 30 minutes and updates it if there is new information after that. This then reflects on the banners being shown depending on the selection made by the admin.
