Alexa ring routine works sporadically

I have a stick up cam at the barn. I have an Alexa routine setup to say "motion detected at barn" triggered by the camera motion. This works when manually executed. It also works as it is supposed to, sometimes.For example. As I walk in front of it in the morning on the way to my run, it executed. An hour later when I return and walk by it again, it doesn't. I'm not sure but it might only execute once per day. There are no time schedule limitations set up.Any ideas? Thank you.
