Bye, bye, ...the day...the Ring Pro Died

I have had the Ring Pro for about 2.5 years. Aside from a few bugs it worked as exepcted. Yesterday it went dead. The app indicated no WiFi signal. Per the instructions, I removed the cover and pressed the side button. No response. No light. No sound. No nothing. So then I thought well maybe it isn't getting power. I checked the fuse in my house fuse panel. All was right. I then removed the mounting screws and pulled the doorbell from the wall. No physical damage and the lead wires were secure. I then loosened the lead screws and disconnected the lead wires. After disconnecting, the ends touched and sparked. The doorbell inside the house rang. The only conclusion I can draw from all of this is that the issue is in the doorbell. It worked without issue for years. Nothing has changed. Anyone else experience this? Any advice? It seems like it should last longer than a couple years.
