My G and Y keys stopped working after I updated to the November 4th firmware. Is there a way to undo this? It had been working fine before it, I have also cleaned it properly and took all the keycaps off but even writing this is hard because when I type GGGGggggggg it just gggggggives me a million of them and I have to use backspace so much. Same thing with yyyyyyyy. The keys feel normal and looked normal when I took off the keycaps, so it’s the only cause I can think of so suddenly.
