You can configure the open and close time for response collection.
If no configuration is made, the form opens when you press 'Publish' and remains open until the author closes it. If the open time is set to an earlier time than the present, response collection will start when you press the 'Publish' button. If the open time is set to a later time, response collection will begin automatically at the specified time.
You can set the open and close time with minute-level precision.
You can also close the survey by limiting the number of responses. The survey closes when either the close time is reached or the response limit is met, whichever comes first. You cannot set the response limit lower than the current number of responses.
