Wall Light Solar Motion / Lights Very Inconsistent

I am looking to build out lighting / security / cameras with Ring but getting frustrated with my first ring test purchase. Wall light Solar is very inconsistent (signal is good, firmware up to date, mounted at the suggested height). Sometimes it does not detect motion, I'll go out and wave my hands around and.... nothing. Other times the app detects motion, but the light will not come on. What is going on? I am bummed b/c I like the design / app / interface, but this experience alongside what I am seeing in the forum is making me reconsider going with Ring.
