Intake Form Submission Fails When Signature Field Is Included (Business Premium Plan)

Hello Wix Team,

I’m reporting an issue on behalf of my client who is using the Business Premium plan.

Problem:
Form submissions from the Intake Form are failing when the signature field is included. The form either does not submit or the submission is not received.

Important context:

  • The forms were working correctly until very recently (within the last few days).

  • No structural changes were made to the form prior to the issue appearing.

Tests already performed:

  • :white_check_mark: Removed the signature field → forms submit and are received correctly.

  • :white_check_mark: Removed and re-added the signature field → forms still fail when the signature field is present.

This strongly suggests the issue is specifically related to the signature component.

Could you please:

  1. Confirm whether there is a known issue with Intake Forms and signature fields.

  2. Advise if any recent updates may have affected this functionality.

  3. Suggest a workaround or fix.

Thank you in advance for your assistance.

Best regards,
Anna
