But when I added data dimension (Networks) and created it from the OrgUnit group set, Show me a message The selected dimensions didn’t return any data. There may be no data, or you may not have access to it.
as shown in the image below :
After running analytics tables export and performing Maintenance (clear application cache & reload apps) from the Data Administration app. Please try to test again by logging into your instance in Guest mode
If there’s still the same issue, could add the steps to reproduce this? Additionally, a screenshot of errors in the Network tab and the console would help.
