To change your attribution window for Meta reports on a workspace level
Note: You must have owner or admin level access to change your default attribution settings in the selected workspace.
Head to the top left workspace drop-down menu
Select 'workspace settings'
Select 'data sources' in the window pop-up
Hit 'edit' on your Meta data source
Adjust your attribution window accordingly and save your changes
Please note: changing your attribution window on a workspace level will apply the saved changes to new reports created going forward. Any historic reports already set up in your workspace would need to be adjusted on the report-level using the steps highlighted in the video above!
