Ring doorbell 2 not ringing mechanical doorbell

Hello, I’ve just installed my new Ring video doorbell 2. My existing doorbell had four wires (an orange and white & a blue and white combination) after wiring these in much in the same way they were to my old doorbell my Ring doorbell works!

However, it’s not ringing my existing mechanical chime. Am I missing something?

Anyone else had this issue?
New build house if that makes a difference.
