Hi, I am trying to apply some styling to the overall look and feel of the app I am building, like background color, font colors and things like that. I have followed the guide on https://docs.mendix.com/howto/front-end/set-up-sass. This all went well, but when I make some changes in the _custom-variables.scss or custom.scss they don't take effect. The colors stay the same. Even when I rerun the app from Mendix Studion Pro. I don't know what I am doing wrong. I hope someone in the forum can give me some tips in this matter. Thank you in advance.
