Display newline inside ion-label

Well, I am again not sure about what you mean by full control, but from whatever you’ve told us about the problem till now I had felt that you might need an arbitrary delimiter character. Perhaps that’s not the case here.

I think @rapropos has already given you the best solution, you should try in-lining the css wherever needed and not use the !important as that’s gonna override everything else and mess up things.

Hola, en tu funcion que tienes el text haz lo siguiente
JSON.parse(this.varMessage.toString());

y en tu css del mensaje utiliza
white-space: pre-wrap!important;
