Name your price subscription

Got an email from Wyze to subscribe to person detection, despite i have 3 of 6 cams are working fine and can recognise persons, i decided to subscribe to encourage them, however. Nothing has changed, only the old 3 has this feature. I made all firmware up to date and my apps on ipad and iphone too are updated even restarted camera with no help. I have cam v2 and cam v2 pan . I am afraid now to restart good working cameras they will lose PD too. Shall i cancel this subscription?
