That doesn't seem quite right. I've been posting videos every week for a year. The evaluation was supposed to be for the last 90 days if you look at the photo I enclosed in my question. The report will only evaluate the last 28 days?? That's a glitch. I've had this feature work well for me last year, now there isn't enough data? Why was there enough data a few months ago, but not now? My channel hasn't changed and I don't have it set to 'kids' and there are no marks on my YouTube account. My channel has over 300 subscriptions and enough views to have enough data.
