storybook v7 beta, viewports and other options disappear on startup

Question

I'm trying to setup my storybook environment and while it mostly works fine, the viewport tab, and other options, disappear on build/start. I'm not sure what's going on here, I haven't seen any information regarding it and I've been removing features from my SB environment to fix it ... so far to no avail. Any guidance would be appreciated.

storybook/preview.js -- emptied it of all content

storybook/main.js (below)

module.exports = {
  stories: ['../src/**/*.mdx', '../src/**/*.stories.@(js|jsx|ts|tsx)'],
  addons: [
    '@storybook/addon-links',
    '@storybook/addon-essentials',
    '@storybook/addon-interactions'
  ],
  framework: {
    name: '@storybook/nextjs',
    options: {}
  },
  docs: {
    docsPage: true
  }
};

step for video below:

1. run npm run storybook
2. open new browser tab

I've just found out that actually after version 7, the viewport button only appear on canvas and not in the docs anymore.
