I returned the device because I was convinced it was broken but the replacement has the same behavior. I don't get it. The Teams-Button does nothing. On my business laptop it is lit purple. On my personal notebook it is not even lit. Answer/End call button the same. Lit on my business PC, dark on my personal PC. No function whatsoever. Ony thing that seems to be doing what it should is the lightbar that glows green on my business laptop and the mute button syncs with teams. No light and no sync on my personal PC.
By the way I am connected via a hub and USB-A (Lenovo Monitor) but I also tried a direct connection and tried Bluetooth with the same results.
I installed the Poly lens software on my personal Laptop and get the red info banner "Network connectivity is not available. Some features may be limited until connection is restored." What does that mean? My internet connection is always on and quite fast. No dropouts or packet losses.
