I called Ring today. They were very helpful. My doorbell isn’t one year old yet, so they volunteered to send me a replacement unit and asked that I send the old unit in for them to conduct an engineering review. They insisted I took some pictures and emailed them the same. Fairly painless and very friendly customer service call center out of Arizona. I suspect that my one year warranty will be up in a couple of months, so when it happens again over the next 12 months, I might be SOL. I’ve already proactively ordered 3D printed replacement buttons. When I run out of options in a year or two, I guess I’ll be attempting to replace a button. Hopefully there will be a YouTube video or an instructible posted before that happens.
