Person detected stopped working

As of 4/22/21, both of our battery operated security cams have stopped detecting people. We have not made any changes in the settings. We only receive “motion detected” alerts now—even when people are in view—rather than “person detected.” We’ve also found that the detection is not as accurate on both cams (there have been times people are directly in front of the cam, and it doesn’t detect them). I have reinstalled the devices and my app, but this has not helped. Any suggestions would be appreciated.
