Help: Form not working from mobile and Safari

Hi,

I have a public form which is the main and single request form for a client. The form is embedded into the client’s website.
We tested the publicized Coda form and it’s not working from Safari (any device) and mobile (any browser) at all.

The Submit button is greyed out even if all required fields are filled out.
We tested from PC and MAC with all major browser types and the same form works.

How can I contact the Coda support to trouble shoot this live? This would be a very urgent one to solve before the weekend, otherwise my client loses the weekend surge in leads…

Thanks!
