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.

    Same setup but my Black widow is on USB cable while my DeathAdder V3 is on wireless.

    The W key will register much slower than other key. It is very obvious when typing "we", it becomes "ew".
