Problem with GA4 2.0 connection

Hi alexvgp ,

You might want to try the following:
- Make sure that both Power BI Desktop and the Google Analytics connector are updated to the latest version.
- Try reducing the amount of data being processed by heavily filtering the data.
- Try using a different connector or tool to connect to GA4, such as Google BigQuery .
