How do I increase the size of my Reply TextArea?

[oga]

Maybe there is something I am doing wrong.

.d-editor-textarea-wrapper textarea {
 height: 250px; /** adjust accordingly **/
}

Is what mine looks like using your snippet. Still the same.

Here is what I did.

I created a New Theme Component,
I added your snippet to the HEAD section of the CSS.
I applied it to both Mobile and Desktop, but still the same.
What have I done wrong?
