How are sessions calculated for widgets?
Sessions are calculated based on Session Lag value of widget loader. Session Lag refers to the number of hours to wait before a visit is treated as a new session. If you set lag as 12, we will treat a user visit as new session only if they have not visited your site within the last 12 hours.
The default session lag value for widget loader is
6. If specified, it must be number between 1 to 24.
