Razer Synapse 3 is not detecting Razer Mamba Chroma & BlackWidow

Shout-out to the community!
I've been experiencing this problem for quite a while and since Synapse 3 is in a long time BETA release I never wanted to raise the topic but it's been quite a while since then and I feel that it has to be addressed.

The 2 devices I am using are:

Razer BlackWidow (original ver)

Razer Mamba Chroma


Based on the official support list here both devices should be supported!? While I have a small doubt about my mouse since it's not the latest edition (it's been already 3 years) it clearly mentions the original BlackWidow keyboard. It doesn't seem like a driver issue since both of my devices were immediately recognised by Windows 10 and updated with their drivers respectively. I tried to repair the software as stated by the troubleshooting article and uninstalled both my drivers and Synapse with no success. As an optional step I tried to use Mamba just wireless mode hoping that the dock will be synced but it didn't help either.

As of now Razer Synapse 2.0 is the only one that works for both devices but all of the updates are done to the new platform. Having a flagship mouse for £135 (RRP at the time of purchase) as well as premium keyboard such issues are really showing poor support as it should work flawlessly at least on the essentials.

Has anyone experienced similar issue? What can be the cause for not detecting officially supported devices?
