Viper V4 not charging?

Seen this issue posted many times with no actual fix. 

Have tried: 

  • Uninstalling synapse and reinstalling it;
  • Updating the firmware of the dongle and the mouse;
  • Closing Synapse when plugged in to charge;

USB is not plugged into a port, it is directly plugged into my PC. The charging indicator lights up on the mouse itself and in synapse but it’s stuck at 50%. The fact that this is still an issue is insane its a $200+ mouse?!
