I have copied a dashboard from AGOL to Enterprise by using this tutorial: https://support.esri.com/en/technical-article/000018924 All the feature layers and the webmap is copied with success.
When I open the dashboard in Enterprise I get this message:
"Error
This is a newer dashboard item version than your app supports. Contact your administrator."
Enterprise has the version 10.9.1.

Does anyone have any idea why this happens?
