Jun has more Users than Mai + Jun
In my Audience Overview in Google Analytics, I have more in the Users metric for the month of Jun alone than I get when I choose a greater period rang (Mai + Jun).
As you can see in the pictures:
I have looked everywhere for an explanation but I couldn't find anything.
Another problem that I have is that when I use a 100% segment (a segment that includes urls matching regex ".*" for example), the total number of users jumps to a figure way higher than before.
According to my research on the web, this might be due to sampling. But I would understand that if it were few percentages higher. In my case, it is a lot more.
Where do you think these problems come from?
It might be worth noting that I the data you are seeing belongs to a view created by someone else and I don't have Admin rights to access the "All website Data" view.
Any clues would be extremely appreciated because I have none.
