Ring Doorbell not Online, but Rings many seconds after button is pushed

I've had the bell about 4 years. Recently, I received a notice that the bell was offline - however, all my ring cameras were online, so clearly not an internet issue. Also, bell light was not on, but when ringing bell, sound would go off 30+ seconds later after pushing button. I'm pretty sure the bell itself is defektive, but how can I be sure?
