It is kind of odd. It seems to be a widespread issue as there have been many reports of this problem, Wyze has duplicated and acknowledged it, however it is not a universal problem. My VDBv1 is crippled by the lack of detection zone function, but it has never experienced 3of3 loading delays and is on the .060 FW.
I think it is a network connectivity issue, but it is rooted in the way the FW resolves the TUTK P2P network connection thru the local network to get the video from the VDB. It just doesn’t like some networks. Just an opinion tho. Some have postulated that it is a power management issue with the types of power supplies used. Lots of theories.
At any rate, an update and links to other topics discussing this:
