As of 9pm Eastern time, 22 minutes ago, my v2 cams with legacy person detection are back to properly recording events labeled Person. 
I did nothing to make this happen so it must be a server fix.
Edit: Adding some screenshots… Under Wyze app Home > Account > Services:
I have a bunch of v2 cams assigned to legacy person detection (Pilot):
Under Settings > Event Recording for each v2 cam, Detects motion is enabled:
Under Settings > Notifications for each v2 cam, Notifications are enabled, but no type is enabled because Person is missing and I don’t want a notification for anything other than people:
But, mysteriously, I’m getting Person notifications. At least it’s working.
