Hi P6onka,

I understand that your Razer DeathAdder V3 Pro scroll wheel is not responding. Were there any incidents that happened to your mouse before the issue? Is there any noticeable physical damage from the device? Is the scroll wheel hard to turn or stuck in a certain way? To isolate the problem, please follow the troubleshooting in this article. Also, check if the problem persists without the Razer Synapse 3. Kindly follow the steps in this link. I'd appreciate it if you could share a short video for our support team's visibility. Share it via PM along with your mouse proof of purchase and serial number for warranty validation. Save the shareable files via any online drive account listed here. All the best!
