I just updated the Android Ring app to v3.22.2 on 2/12/2020, and now it does not show the firmware version number of my Ring Doorbell Pro anymore. It just says "Up to Date".
@Ring, "Up to Date" is a commentary on the firmware version number, not a version number. Please include the firmware version.
Last I checked, I was at v2.1.01005, I think.
