Mechanical door bell doesn’t ring

Door bell doesn’t go ding dong! I have a video Pro, wired to a Nutone mechanical doorbell. I replaced the original 16vac 10VA transformer with a 30VA transformer. I did the install using a jumper wire. The mechanical doorbell does not ring when the button is pushed. Notifications occur on the phone, but no Ding-dong. It is worth noting that this is a reinstall. The same video pro device at the old house rang the doorbell. At this house(new construction). It will not ring the doorbell. What good is a fancy high tech doorbell button that won’t ring the doorbell??? I don’t carry my phone with me everywhere I go in the house.
