Razer Viper V2 Pro dongle stopped working out of the blue.

Good afternoon,

My Razer Viper V2 Pro mouse dongle stopped responding out of the blue. I’ve had this dongle plugged into my motherboard usb slot w/ a clear line of sight to the mouse for 3 years since purchase. I tried repairing it w/ the pairing utility, reinstalling mouse drivers, factory resetting my mouse, & tried w/ the dongle plugged into my work laptop; no luck. Updating the firmware for both my Mouse & Dongle claims the dongle is not plugged in. The mouse works perfectly fine wired. 
Have there been any successful resolutions to this issue? Or is this just an issue only Razer seems to have & they couldn’t care less?
Edit: Some of the more recent threads about this issue seem to be being addressed, so I wouldn’t say they couldn’t care less.

Hey there, ​@ToadBalls 

I understand that your Razer Viper V2 Pro dongle has stopped responding despite the troubleshooting steps you've already performed.

Could you please send me a PM along with the mouse's serial number so I can check its details in our system and assist you further? Also, kindly confirm the following: 

1. Does Device Manager show the wireless dongle when it is plugged in?
2. Do you hear the Windows device connected/disconnected audio cue when the dongle is inserted?
3. Does Device Manager show any error messages or unknown devices related to the dongle?
4. Is the dongle not detected at all in Device Manager?
