I'd like to change my rating from 1 to 4 stars. Main reason why is that the guys at "themelooks" reached out and responded. I was able to install the Theme successfully on older versions of WP up to 5.0.3. An update would be in order, and that's why I give it 4 stars (even though I think the idea of the theme is great), upwards compatibility and UX could be improved.
