Diagnose Marketing Dashboard Data Access

1. Reads the dashboard errors on the Marketing Intelligence home page and checks setup prerequisites, such as whether the Marketing Performance app that creates the semantic model is installed and whether the engagement data has any rows.
2. Fixes configuration gaps it can reach, such as currency setup with dated exchange rates and the industry type.
3. Traces semantic model deployment errors back to the data in Data 360, such as a failing DLO/DMO sync, and shows when a disable and re-enable cycle does not clear the failure.
4. Traces display errors after an upgrade to a changed page URL, writes up the root cause analysis, updates the navigation references and confirms the new page loads.
5. Stops and hands over when the fix needs the browser UI or Salesforce Support.
