The newest Synapse Update has been causing a ton of issues. I have a Naga v2 Pro, Tartarus Pro, Blackwidow Chroma V2, and Leviathan V2 Pro - all have been acting up since the recent update. The Naga frequently can no longer go wireless, the Leviathan and Tartarus are frequently disconnecting for a few seconds before reconnecting, and some of the macros on the Blackwidow will randomly not work. All of them were working perfectly fine before the update.
