I want to retrieve Facebook Ads budgets from my text string. When I extract them, they are duplicated by date, so I use MAX to eliminate the duplicates. However, I can't sum the values because Looker Studio can't double aggregate. Is there any other solution to sum MAX, like in Power BI?
Not that I know of, but this would be a good feature request! A duplicate removal function or double aggregation would address your issue, I think.
