I started carrying my Macbook around, I used too have a Macbook Air for school/carrying around etc., never used to carry my actual device, but it turned out to be fun and productive while it lasted
For some time I was wondering why "CMD+V" doesn't work with the built-in keyboard, today, when I was using the device for some light stuff, it started bothering me a lot, it then dawned on me that it could be "V" that is problematic, and traumatically, indeed it is
Then stumbled onto this:

It seems the Butterfly keyboard is pretty problematic, while writing this, I noticed that my "O" key is also similarly problematic, don't know why but it seems a decay has started, both keys only work only if you hit or press it super strongly, rather than tapping the key - I have a US device in TR, probably can't get it easily serviced, even if it was possible, I read that the service takes 5 days and the entire upper body gets changed
It's such a F* Apple moment, I had to buy this device because the previous one had it's battery swollen right after installing High Sierra, and now this stupidly annoying keyboard issue ...
(Edit: If it happens to anyone, applying a lot of pressure to the key seems to fix/delay the issue)
