Thank you for reaching out and providing us with your feedback. Our Meridian team always appreciates different perspectives from publishers on how we can enhance the overall user experience.
I want to make sure that I completely understand your requests so that I can pass them along to our dev team. Within the main dashboard, there is a timeline dropdown that allows you to view your total earnings over a multitude of custom date ranges including daily, weekly, and monthly statistics. This is the best way to see your total earnings, impressions, requests, average fill rates, and CPM's across all tags, geo’s, and devices. The downloadable reports are meant to give a more intricate breakout of these metrics which is why you have the ability to separate it by tags, geo’s, devices, etc.
I love the idea of breaking out geo reporting by country as well! This is something that our data team has been looking into as we continue to build on our international reach.
If you have any further questions or concerns please do not hesitate to reach out to us directly at firstname.lastname@example.org.
