Firmware update notification stuck + W key cutting out – only with multi-device pairing (BlackWidow V4 Pro LP TKL + DeathAdder V3 Pro)

Hi everyone,

I'm having two issues with my Razer setup and hoping someone here can help:

1. Persistent firmware update notification:
Whenever I pair my Razer BlackWidow V4 Pro Low Profile TKL and my DeathAdder V3 Pro together using the multi-device pairing feature (both devices on one HyperSpeed dongle), a firmware update notification keeps popping up and won't go away.

2. W key randomly stops registering while gaming:
In this setup, the W key (held down) also randomly stops responding while gaming and the input just cuts out. It happens irregularly and without any obvious trigger.

Important detail: Both issues ONLY happen with multi-device pairing. As soon as I connect each device through its own USB dongle instead, the notification disappears and everything works fine.

My setup:
- Keyboard: Razer BlackWidow V4 Pro Low Profile TKL
- Mouse: Razer DeathAdder V3 Pro

Has anyone else run into this with multi-device pairing? Is there a fix, or is this a known bug?

Thanks in advance!

    I also have the constant firmware update notification, only if I do multi device pairing with my basilisk v3 pro mouse dongle. If I use the keyboard dongle the notification goes away. 

     

    I have not had the w key dropout issue but then I don't really game with the keyboard so maybe I'm just not noticing it. Never had that problem.when typing.
