Doorbell Pro pressed causes chimes to hum loudly

Ring Pro has been losing power and has to be disconnected from the transformer and reconnected to work. Then it will lose connection usually when pressed. Now when pressed it no longer works and causes the chimes to hum, indicating a fault in the doorbell button. I have had it since 2016. I have replaced the transformer with the recommended transformer. Has anyone else experienced anything like this? Is there some type of resolution? I like Ring so much I got their 2nd Gen alarm system. Now I need to get my doorbell working again.
