The reason for this issue is that the preconfigured Insights reports need to be modified to meet GDPR requirements. Insights is a feature that allows you to measure and analyze the adoption and engagement of your Experience Cloud sites using preconfigured reports and dashboards. However, some of these reports may not comply with GDPR, which is a regulation that protects the privacy and data rights of individuals in the European Union. To use Insights for the Experience Cloud site for Europe, the Community manager needs to modify the preconfigured reports to meet GDPR requirements, such as anonymizing user data, obtaining user consent, and deleting user data upon request.
