I know there are countless posts about the butterfly keyboard and need to get the top case replaced, I searched and most are years old. I've had the keyboard (top case) replaced once about a year and a half ago and since then, have returned to the "Genius Bar" countless times to report space bar sticking and the letter "M". I've had it cleaned 3 times, and told that I can either pay $600+ to replace the top case or trade in my perfectly working computer for $500. Its ridiculous that I would have to pay to replace, yet again, the butterfly keyboard when it is a known defect. I have tried reaching out to corporate just to get a canned response, that I am out of warranty and I have no options but to pay to replace. Has anyone worked with a senior advisor and had success replacing it a second time on Apple's dime? I'm incredibly frustrated and refuse to pay a penny to fix their issue. Help?
