Issue with Date Format Validation on Adobe Sign Webform (Mobile)

I created a webform template on Adobe Sign with data validation set for the YYYY-MM-DD date format. However, when users fill out the form on mobile devices, the date field opens a calendar picker instead of a text input. The issue is that the selected date automatically formats as YYYY/MM/DD, which does not match the validation rule I set (YYYY-MM-DD). As a result, the form fails validation, preventing users from submitting it.

Has anyone else encountered this issue? Is there a workaround to ensure the date picker respects the YYYY-MM-DD format or a way to modify the validation rule to accommodate mobile formatting? Any insights would be appreciated!
