The Credits Activity or Credits Turnover page for an individual member, (here, calculates DirectCam figures based on the End Date of the DirectCam Session.
The Group Credits Report, here, shows figures based on the Start Date of the DirectCam session.
What this means is that sessions that start before midnight and are complete after midnight will appear on one day on the Credits Activity report and on the Group Credits Report they'll appear on the day before.
We appreciate this is confusing but will not affect a change at this late stage as it could result in more confusion and incorrect payments to group members.
