Ring Pro reboots when button pushed, app no longer shows voltage

I have a ring pro that is 2.5 years old and has a cracked button (sound familiar?). It has been working fine until recently. When the doorbell is pressed, the unit hangs and reboots. Sometimes the notification makes it to the phone before it reboots, sometimes it doesn't. After a couple minutes, it's up and running again until someone pushes the button. Live view and history work fine. When I check Device health, it shows signal strength (which is fine), however the app no longer shows what the voltage is. The word "voltage" isn't even in the menu. I know it used to be there, but now its gone. When I click on "Device health Report", it says "its power level is undefined." Where do I go from here?
