Hi I stupidly updated to Razer Synapse 4 last night (from 3.) Now today when I login I've realised my Naga V2 pro is suddenly extremely laggy. Its scrolling and selecting stuff on its own also. It was absolutely fine before I installed Synapse 4. Naturally I tried uninstalling Synapse 4 but the issue persists. I’ve uninstalled mouse drivers, I’ve ran the the driver cleanup tool, I’ve ran the firm wear update, i’ve turned it off and on again like 5 times. I’m not really sure what else to do. I’ve only had the mouse 1 month and I am absolutely sure the Synapse update from 3 to 4 did this as its the only thing that changed since I went off last night when it was working perfectly.

I noticed while I had Synapse 4 installed that it was like the mouse kept disconnecting and disappearing from the list. The mouse itself was also constantly flashing its lights on and off.

Now I can’t use my mouse wirelessly. It only works if I turn it off and plug it in directly. There doesn’t seem to be a way to go back to synapse 3. How do I fix this?Has anyone had any success?  An what has even happened to my mouse?!

I don't want to speak too soon but maybe I fixed it? It was the wireless power saving mode. It was set to 1 minute, I changed it to 15 and now its not flashing and disconnecting every second.
