Adding phone to newsletter form

[absolute_il]

I am looking to add a phone number to my newsletter form. 

It looks like using `name=contact[phone]` doesn't save the phone. I verified on Network tab that the phone is submitted properly on `contact[phone]`. 

I also saw posts that suggest saving it on Notes. IMO it's not an acceptable solution. 

Can someone from Shopify's dev team please take a look at this subject and find out why it's not saving? 

Code:

    <div class="fieldset" style="justify-content: normal;">
                ...
                {%- assign phone_label = 'customer.addresses.phone' | t -%}
                {%- render 'input',
                  type: 'text',
                  name: 'contact[note][phone]',
                  label: phone_label,
                  type: 'tel',
                  autocomplete: 'phone',
                  required: true
                -%}
              </div>

IMO, if `notes` works, it means that the issue is on Shopify's backend not mapping correctly `contact[phone]`.

Solutions that doesn't work:

1. input type as `tel` instead of `text`

2. Saving on notes

@absolute_il , hi, have you found a solution?
Need the form, that takes user's name, last name, email, phone, email subscription, SMS subscription. Can't find how to capture the phone and SMS marketing.
