My floodlight is also from Oct 2019 but we just installed last week. I replaced an older style flood light with Ring floodlight. My old light only came on when detecting motion. Ring was coming on constantly or staying on.
I’ve adjusted the light settings and am hopeful that tonight the light only comes on if it detects motion. Thanks for the tip about light settings. I haven’t mastered all the bells and whistles yet and thought motion and light sensors were all tied together. Good to know! Thanks!
