Wrong data integrated

Hi NewTechGirl -If Plex Connect has multiple environments (like test, development, and production), make sure you’re connecting to the correct environment. Sometimes ODBC connections default to test environments that contain sample or dummy data.

Review the connection properties in Power BI and in the ODBC Data Source Administrator to confirm they match your actual production database settings.Consult with your Plex Connect admin to ensure your account has access to the correct datasets and that you are connecting to the right environment.

Ensure that you have the latest ODBC driver from Plex, as older versions may not support all dataset structures or may default to sample datasets.

Hope the above details helps to sort out the issue.
