YouTube themselves are not updating Channel view counts at this time. This means that if you go to the about page on a YouTube channel today and look at the total views, it is not changing. The number is frozen.
​
With the source (YouTube) not updating channel views, we have no daily change data to show. This is why there will be a 0 showing for these days.

We do hope that Youtube update their channel view counts soon and will continue to monitor this.
