why do my customers see a "please wait" instead of a successful submittal when they fill out my form?

Hi,

Thank you for contacting us.

I've cloned your form and I was able to replicate your issue, I remove the actual integration with Stripe and re-integrate it again, and it's working on my end.

You can see my sample form here :

Let us know if it works, if not we will be glad to assist you.

Regards.
