also, seeing this error message trying to discover metrics automatically with google analytics

Hey Danny - typically this is due to not having a default data set specified for the data source. If you go to the data source and click "Edit Connection Info" you can enter the data set where your GA4 events are stored. After that, to confirm it worked, you can click on the "View Schema Browser". There might be a lingering error message, so just click the "Retry" button. After that, auto metrics should work. We are working on revising the flow as it's not intuitive that the default data set is required for auto metrics.

Thanks!
