Ring doorbell 4 stopped ringing

Hi my Ring doorbell 4 has stopped ringing when people press the button. The battery is charged and it is connected to the WiFi. The tinkle works to tell be someone is there but not the bell.

Hi @user31720. Do you have your Video Doorbell 4 wired to a compatible chime kit? If you have the Doorbell wired to a chime kit, is it the chime kit or the Doorbell itself that does not ring when the button is pressed? Additionally, do you receive a notification via the Ring app when the Doorbell button is pressed?
