People.increment does not send any network request

I set up my project with people.set() on the login form and people.set() works flawlessly, recording all the information on new users. Including setting the initial value of some incremental properties I wish to track about a user. 

mixpanel.people.set({
            "$email": this.state.email,   
            "sign_up_date": signup_date,    
            "registration_method": "email",
            "generator_started_count": 0,
            "snippet_generated_count": 0,
            "snippet_copied_count": 0,
            "snippet_saved_count": 0,
            "login_count": 0,
            "plan_type": "free"
          });

When one of these actions is taken the event is tracked - which also works, and I can see the event in my dashboard for that user. 

var mixpanel = require('mixpanel-browser');
mixpanel.init("<my ID>");

let actions = {
  track: (name, props) => {
    if (env_check) {
      mixpanel.track(name, props);
      console.log(name);
      console.log(props);
    }
  },
  increment: (name) => {
    let response = mixpanel.people.increment({name: 1});
  },
};

export let Mixpanel = actions;

Called with

Mixpanel.track('snippet_copied', {'copy_type':type });

The problem is with mixpanel.people.increment()

No matter what I do, a network request is never sent to mixpanel.

Mixpanel.increment('snippet_copied_count');

A response is created but never sent in a network request to mixpanel.

$add:
 name: 1
  __proto__: Object
  $device_id: "<MY DEVICE ID>"
  $distinct_id: "<MY ID>"
  $token: "<MY TOKEN>"
  $user_id: "<MY USER ID>"

I’ve also tried, making the increment function the callback to the track function, and I have tried making sure mixpanel is loaded with the code recommended in this post, to no avail. 

Thank you in advance for your help.
