Why is angular cli not including my component scss?

Late to the party, but came across the same thing. Throwing this out there as another option for someone who comes across this thread.

Everything was rendering, styles were getting written as mentioned above, but nothing was actually showing.

Found this article on Shadow DOM Strategies that solved my problem.

Specifically setting encapsulation: ViewEncapsulation.None made styles show correctly for the given component.

import { Component, OnInit, ViewEncapsulation } from '@angular/core';
