WHat is the FW version of the v3? I am not experiencing this issue, but I also Beta test Firmware.
Current Production FW for the v3 is: 4.36.8.15.
One of the thngs I would try is to move the Access point to an opposite wall. I have seen where you can over power a device if it is too close to the WiFi Source. Moving the WiFi may alleviate this issue. Also, make sure it is indeed connected to the Access Point closest to the v3.
To see if it is the v3 Camera and the location it is at, move it to the center of the room where there is no walls around it and then test to see if the issue is still present.
Last option to try is to unplug the power from the camera, wait for about 15 seconds and the connect the power again. Once it is fully up, test to see if it still hesitates.
