We are very sorry if you find our theme difficult. But we are ready to do our best to help you and explain all the settings you need and guide you. So, feel free to create topics and ask everything you need to clarify.
1) Could you please, tell me what page builder you chose: WPBakery or Elementor while importing demo content? What home page would you like to use?
2) Provide us with WP Dashboard access to your site to check your permalinks. Permalink settings are default WordPress settings and our theme should not cause any issues with that.
