During the initial setup for Poly Studio V12, the "Static" IP network parameters are not saved after the first attempt when applying the LAN configuration, but this works on the second attempt.
If the 802.1 and Proxy settings are configured on Poly Studio V12 through the Poly Lens Desktop app, the changes won't be visible in the App UI after saving if the device firmware is at 1.4.6.430149 or lower.
Once the software for HP 960/965 cameras is updated, the Poly Lens Desktop app must be restarted to display the updated software status.
