You don't need those styles duplicated in previous place anymore.
Can you link the documentation for putting styles in app.component.scss?
Not sure I got this. We have demos that uses that approach, but what kind of docs you meant?
I was about this guide https://bryntum.com/products/gantt/docs/guide/Grid/customization/iconfontupgrade
But you're right, there is nothing about app.component.scss
. There are no requirements where exactly should that be placed, it was mentioned to demonstrate it works well in very simple application, so that doesn't look like our bug. I think you just need to check/compare the order or loading CSS in your initial app and make sure all paths are correct.
All the best,
