All Sensors Disappeared from App

In the Ring app, I can arm my system, disarm it, and I see a message right under the Armed indicator icons "all sensors cleared". But ALL my sensors have disappeared from the app. I have several motion sensors and 4 door contact sensors. This appears to have have corresponded to getting an Astro. The only device the app shows is Astro, it appears as a "Camera". I wish Ring put as much effort into making the App work properly as they do to pushing banner ads into the app. It is very frustrating to try to troubleshoot with ads and other marketing come-ons popping up as I work in the app.
