I've had a lot of approvers say that there has to be an easier way to review if there is a conflict when they get a request. The last system we had allowed you to look at the request in conjunction with the calendar and how it fits with other appointments for that particular space and day/time without much fuss.
Hello,
When an approver gets a request and open it to move the status - there is a conflict icon directly at the top-right. Once that is clicked they can view any reservation that is conflicting with the reservation they are working on.
Can you give this a shot and let me know if that works?
