This happened to me twice last week, happened yesterday or 2 days ago as well. I don’t think this is fully resolved, because 2 days ago was December 1st and this issue was marked as solved on November 29th…
Every time, I had to upgrade the firmware via https://user.wyzecam.com/upgradedevices. Haven’t had this issue in the past and there’s nothing wrong with set up or internet connections. I have other cameras in the house and they all function fine.
