Got a new 2017 MacBook and I noticed two issues. One of the keys was not working reliably and the keyboard was leaving imprints on the screen. Nothing is placed between the keyboard and screen. Laptop is carried in a sleeve. No pressure is placed on the laptop. Took it to Apple and they replaced both the keyboard (top plate?) and the screen. Now just a few days after getting it back, I am noticing imprints again on the screen. What gives?
