how can I deal with problems in reading the submissions

When I reviewed the submissions (Earth in five reactions), the form repeated stopped responding. Each time I have to start from the latest form and click ">" many times to advance to the unread submissions. How can I deal with the response problem and advance directly to the unread entries? 

Do you mean while in https://www.jotform.com/myforms, you want to jump to a form with unread submissions?

If so, you can follow the steps below to make your form with unread submissions appear on top.

If you mean something else, please give us more details.
