title: User Meta option and hooks not working for Gravity Form User Registration Addon
body: <p>I'm using the Gravityforms User Registration, <a href="https://www.gravityforms.com/add-ons/user-registration/" rel="nofollow noreferrer">https://www.gravityforms.com/add-ons/user-registration/</a> plugin to create a custom registration form. And this form is linked to a woocommerce product using Woocommerce gravityforms product addons, <a href="https://woocommerce.com/products/gravity-forms-add-ons/" rel="nofollow noreferrer">https://woocommerce.com/products/gravity-forms-add-ons/</a> plugin. I need to update a user meta field using a field value from this gravity form for the newly registered user. For this, I have selected the required User Meta options from the gravity form settings in <em>Forms -> User Registrations</em>. 
  After purchasing the related woocommerce product after filling this gravity form on it, the user is creating successfully. However, the selected user meta for this new user is found to be not added.</p>
  
  <p>Tried to add the same using the following hooks available with Gravity Form User Registration Addon within our custom plugin.</p>
  
  <ul>
  <li>gform_user_registered
  <a href="https://docs.gravityforms.com/gform_user_registered" rel="nofollow noreferrer">https://docs.gravityforms.com/gform_user_registered</a></li>
  <li>gform_after_submission
  <a href="https://docs.gravityforms.com/gform_after_submission/" rel="nofollow noreferrer">https://docs.gravityforms.com/gform_after_submission/</a></li>
  </ul>
  
  <p>However, all the above hooks were found to be not working.</p>
