Custom Styles overridden by Styles

Hi!

Since I migrated my project from the beta.11 to the released 2.0.0 version.

I have a buttons.scss file in /src/theme/ and I want to apply this style to be used throughout the application.
I’m importing it in the variables.scss file. However, no matter where I place the import, this styles are being overridden by Ionic’s default styles.
Is there anyway to make this work?

Thanks
