Limitations of Data Sources Handled by Looker Studio

Thank you @sam8 for your response!

To clarify, my question is not just about the availability of connectors, but also about data blending capabilities in Looker Studio. I want to create a complete dashboard that combines multiple data sources.

For example, I need to calculate the total budget spent, which means summing up the budget from Google Ads, DV360, Meta, Pinterest, and Criteo. Can Looker Studio handle this type of data blending across different sources? If so, what is the best approach to ensure accurate aggregation and avoid data mismatches?

Thank you again for your help.
