Razer DeathAdder V3 HyperSpeed multidevice not working properly

So I have a Razer DeathAdder V3 HyperSpeed and a Razer BlackWidow V4 Mini HyperSpeed that I’d like to use with the same dongle.

When I pair the BlackWidow to the HyperSpeed dongle of the DeathAdder, the RGB defaults to spectrum cycling and cannot be controlled from Synapse. When the pairing situation is reversed, the mouse disconnects randomly.

How to replicate the lack of RGB control:

1. Connect the DeathAdder V3 HyperSpeed mouse dongle to the computer
2. Open Synapse and run the Pairing Utility to pair the keyboard
3. Once paired, Synapse will not be able to control the RGB on the BlackWidow V4 keyboard

How to replicate the random mouse disconnections:

1. Connect the BlackWidow V4 Mini HyperSpeed keyboard dongle to the computer
2. Open Synapse and run the Pairing Utility to pair the mouse
3. Once paired, the mouse will experience random disconnections

I tried pairing the  BlackWidow V4 keyboard to the dongle of the Orochi v2 mouse that lives in my laptop bag and it works perfectly.

However, pairing the Orochi v2 mouse to the BlackWidow V4 keyboard dongle results in random hiccups.

I’ve updated all mentioned peripherals to the latest firmware as of the publishing of this post and said updates can be found in the following links:
