Why the total numbers of by day data not equals to by month data with the segment of "last month"
Hi all
I'm trying to see the data of some key metrics such as "PV", "UV" and "Bounce Rate"...
But I notice that when I use the default segment of "last report month", the total by-day data was not equal to the by-month data for nearly all the metrics.
When i look to the "Month" data, the data showed correctly.

But when i look to the by day data, less data was show on the table.

But when i combine two dimenssion together, the by day data showed correctly again.

Could anyone explain to me why this happen? It will be really helpful.
Thanks QAQ
