Web site still failing. This app has never worked well when attempting to manage devices or authenticate with the server. It's generally reliable switching between my two existing devices. Today, I received a replacement device due to the recall. It paired successfully but the app has no ability to add a new device, remove a device, etc. I even tried creating a new account and that kept failing at the server. I've been SW engineer for 35+ years. I'd be fired if I'd written something this bad.
