Form get stuck on waiting after submit button is pressed

hi

i have several folks who are unable to fill out forms and submit.  It gets stuck on waiting after submit button is pressed.  I tried and I'm having the same issue.  Please advise. 

Thank you

I just noticed that you have a number of forms in your account. And as I am not able to replicate the issue on my end, can you share with us the link to the form and/or the page where this problem happens?

Looking forward to your response.

Thanks.
