I've recently had a massive issue where 90% of the keys aren't working properly. "W" for example works fine but "4" has to be pressed 5-10 times for it to work, some keys stopped working altogether, the issue is happening with every key, i tried putting it in demo mode and back in normal mode, tried uninstalling synapse 3, uninstalled drivers as well but still the same issue, any ideas? the issue started about a year ago and i just put the keyboard in storage and used another keyboard but I'm trying to fix it now, please help
thanks
