Problems update software

Hello,
I am currently using the wyze cam v2 camera and have updated to the latest software. My camera is turned on but when I choose person in the event I just see the intro to cam plus. I do I get this feature back. I already made a contribution awhile ago and I did see it working but now it is gone.
How can I get this feature back.
Thanks

Click on account in the app, then services, then person detection and you should be able to turn it on for the cams through there.
