Formstack form required fields do not validate

Validation fails on fields that are prefilled.

Reviewed March 26, 2024

The Issue

Formstack forms support validation; e.g. an email field value must be a 'valid email address'. They also support prefilled values, such as when the user's details are already shown in the form: name, email, department...

Recently authors have noticed validation can fail for some prefilled fields.

Workaround

This appears to be a bug with Formstack forms.

The workaround is for users to click into each 'invalid' field and gently tweak the information; e.g. typeover the last character of each field value.
