Do you need an Adobe Sign license to use "Reusable layer of form fields"

[Randy22547548eaui]

I currently have an Adobe Acrobat Pro subscription license. This is supposed to include Adobe Sign.  I have the ability from the Adobe website to create and use Adobe Sign templates and other Adobe Sign features. But when I try to use the "Apply a reusable layer of form fields" feature, I am missing the "Field Templates" pop-up option.  I found the reference to this feature here: https://helpx.adobe.com/sign/using/form-field-template.html

Do I also need to have an Adobe Sign license to use this feature, or has this feature been removed?

Thanks for any information that can be provided.

The version of Adobe Sign that comes with Adobe Acrobat is the limited Individual plan see

As you will see (from the link provided above)  you have a limited feature set and would need to upgrade to a different plan.
