Why is c211 version 3 video is poor, blurry, less detailed compared to my c211 v2? New version should be better compared to older one.. Thinking of returning this to the store. video settings and fps

I am reaching out here because the local support in my country has not been able to address this issue. I have a Tapo C520WS V2.0 on a wired LAN connection. I am currently on firmware 1.2.1 Build 2509
