I'm wondering if anyone else has the same problem:
Using the Supermetrics Google Analytics connector for Google Data Studio, I created a data source made up of multiple GA properties. It was a simple time series chart where dimension is date, broken down by GA views, metrics is users. It looks fine until I add a filter control to it. Applying any filter only returns a few days worth of data, which is incorrect. For example, applying traffic source = google / organic only returns a few days worth of data such as screenshot below. But in GA those sites always have users data from organic google search. Any guidance please?
Thanks for your message, and sorry for the issue.
Please check your filter by for example fetching the Source / Medium values for the GA views into a table chart, to see the actual results.
You can also try creating a new graph, or whole report - looks like something is jamming that graph.
I tested the filter in our environment, and seems to be working:
