If you're looking at this by day, it's possible that a visit could start on one day and continue to the next. For example, if I come to the website at 11:55pm, and stay on the site until 12:15am, it's one visit, but it spans two days. So in a table where you're looking at it by day, that visit will be counted in both rows/days. The grand total at the top should give you a deduplicated amount.
That makes sense, but in many cases I am seeing something like the following. Session starts at 12:03 PM that lasted for about 6 minutes as a session (looking in our session replay tool). If I look at that in adobe for Visits within the 12:00 PM- 12:15 PM time range, it shows 3 visits. Looking though it is a native mobile session with embedded web views. So its going native, web view, native, native, web view for example. Would each new web view count as a visit? I know comparing tools is not the way to go but from what I am seeing it seems like this would lead to elevated visit numbers.
