Hello my Razer Nari ultimate stopped working with dongle. It keeps beeping and disconnecting shortly after plugging in the dongle... sometimes it works for few minutes. I tried the dongle recovery also reinstalled all the drivers and synapse without any success. I ve seen more posts about it and wanted to buy somewhere the replacement dongle but its not in razer care shop anymore. Is there any way to get replacement? There is nothing wrong with my headset it worked flawlessly until this started to happen. On the cable the sound is not as good as you cant access the synapse settings. Thanks
