Android app won't "rotate"

I am surprised that the current Android app always displays in "Portrait" mode. It does not "rotate" to "landscape" mode like most other Android apps and the Android home screen, etc. Has it always had this limitiation, or is it some recent regression? I tried two different Android devices (phone and tablet) using two different Ring accounts, and some variations such as starting app when already rotated (vs rotating after app was already started).
