Count me among those whose Pro doorbell became much more sensitive a few weeks ago. It didn’t matter whether it was set for people mode or not (and when it wasn’t, the sensitivity slider was at minimum). The previously fine motion zone started getting triggered frequently, apparently by plants swaying in the breeze or cars driving by that were outside of the motion zone. What’s worked so far was to scale back the zone to get it further from the apparent triggers. My only concern is that now it might be less likely to detect an actual person.
