I disassembled "n" a couple weeks ago, not just removing the keycap, but the entire butterfly mechanism. Cleaned up then reattached using glue. Works fine now.

I disassembled "n" a couple weeks ago, not just removing the keycap, but the entire butterfly mechanism. Cleaned up then reattached using glue. Works fine now. As far as I can tell, the mechanism is too fragile / shitty. There is a single metal dome below the key which acts like the spring and actuator. Butterfly thing is there to keep the keycap in place and distribute pressure so if you hit a corner it directs that to the dome thingy. That metal dome seems to have an issue with heat as most people report problems when the device heats up. Maybe it expands. If you look at the contacts below it looks like there is too little margin for error. I think this keyboard is gonna create a lot of issues in the long term.
