I was told the window was shortened concerning rapid session giving, however, even hours later, the system won't allow the same gift to be giving. Sometimes we either take up a special offering later in the service after the main offering, or we have a second service (evening service). In both cases an individual may choose to give the same give. But as of right now, the second gift will not be accepted. Also, the user will NOT know that there gift did not go through. At a minimum, they should be warned and possibly allowed to push through the second offering of the same amount.
