Is it just me?
I haven’t had any Alexa person detection announcements in about 24 hours.
Might be my bad luck because I recently changed back to using the Devices, Cameras toggles for it, after having had middling results doing it via Alexa routines.
Disable and re-enable Wyze skill in Alexa app. Try it and see if that works.
Thanks. I would have suggested the same thing to someone else. 
I’ll let you know if it helps.
Still silent here. I guess I should delete the cameras in Alexa and rediscover?
