No doorbell ring tone on iPhone when button pressed

Hi. Possibly a bug here. My ring doorbell 2 stopped making the ring tone when someone pushed the button. It was sending a screen notification. The 2 chimes in the house were ringing as expected. The issue was the Apple Watch notification was set on in the watch app. As soon as this was disabled the ring came back, but I’m obviously not getting watch notifications. This just suddenly occurred a few weeks ago. Looks like a bug in a software update. I hope someone from ring sees this and can get it rectified. Cheers
