You can cancel a request at any time.
Cancel while waiting to connect
If you are waiting for an available expert to connect, but you decide to cancel your request (for example, if it is taking longer than you expected), click Cancel in the waiting screen. Unity Live Help stops the search and stop broadcasting the request.
If you still need help, schedule a session so that Unity Live Help can send your request to all the relevant offline and busy experts.
Cancel a scheduled session
To cancel an upcoming or pending scheduled request, open your profile and select My Requests, then go to Open Sessions to see all the upcoming and pending requests.
Hover your mouse over the request you want to cancel. Unity Live Help displays a Cancel button. Click it to cancel your scheduled request.
