Have Authorize.Net payment form, Mutiple submissions

We have an Authorize.net account, and while using gravity forms, people can submit payments. This is working well, however, there are some customers, that end up have mutiple transactions being processes. We think it has to do with the browser (probably mobile) that tries to refresh the last page they were on, wen opening it up again, thus resubmitting the previous transaction.

Any ideas on this, or how to resolve it. I would think a token or cookie would be expired by the second transaction or cleared, but have been able to reproduce. Is there a setting or a redirect thats necessary. Perhaps to a different page, as opposed to a message? Thoughts?

Hello. I recommend opening a support ticket for this issue. They may have a fix you can test out:
