Hello, I am a bit confused because we’ve noticed a slight difference when analysing datas. For example when we took datas months by months and comparing these datas to the same month range the values differs. Is that because there is a difference in unique visitor counting depending on the selected month/date range ? thank a lot, ---

Hi @Alexia, Hope you’re fine! Could I ask you for instance and property name in DM as well as dimensions that differs? I will take a look and let you know what might be the reason ---
