Enable responsive friendly upload doesn't generate images

I am trying to restrict the images sizes of media library uploads through the use of breakpoints.
My config/plugins.js looks like this

module.exports = ({ env }) => ({
  upload: {
    provider: 'azure-storage',
    providerOptions: {
      account: env('STORAGE_ACCOUNT'),
      accountKey: env('STORAGE_ACCOUNT_KEY'),
      serviceBaseURL: env('STORAGE_URL'),
      containerName: env('STORAGE_CONTAINER_NAME'),
      cdnBaseURL: env('STORAGE_CDN_URL'),
      defaultPath: 'assets',
      maxConcurrent: 10
    breakpoints: {
      large: 1200,
      medium: 800,
      small: 480,

And on the admin panel I have enabled responsive friendly upload option. However strapi does not resize the images uploaded from the admin panel media library. I don’t think it ever did work because even though the feature was enabled I don’t see multiple images generated by strapi on media library.

Can someone point me in the right direction please.

Thank you.
