I have had my new MacBook Pro 13" with Touch Bar for a few months and love it! There is one problem that has come up though. It's with a few keys on the right side of the keyboard. It's barely noticeable but it feels as though the "L" key and a few others randomly feel squishy and softer than the rest when I type on the keyboard. Is this common? Should I take it to Apple? Is it likely that I just need to clean with some air or underneath the key itself?
