Reports aren't accurate until 10 AM EST each day for the previous day because of our advertisers' reporting schedules and when they finalize numbers. 

If you're checking before then, you're going to see very inaccurate numbers. If you check again after 10am EST, you should be much happier with your results. 

We'd be happy to confirm that nothing is wrong, though, so please feel free to reach out to publishers@mediavine.com and we can check for you!
