What's Wrong?

"Use Ctrl Enter To Send" worked perfectly until a few days ago where the whole UI got revamped.
I'm still able to insert a newline with a simple press on the Enter key, but CTRL+ENTER became stale and is not submitting the prompt anymore.

What Should Happen?

CTRL+ENTER should submit the prompt.
