The problem is, many of us with this problem cant afford to give up the device for the amount of time it takes Apple to fix it.
I've owned a 2013, 2016, 2017, and 2018 MBP (most of them through work).
I'm typing this message on a 2018 MBP, which wasp urchased 3 months ago, and I've decided that I'm not . going to go back and fix all of the sticky spaces that it errantly injects. I could take it in, but then I'd h ave to give up the device for a few days, and its my work machine.
The 2017 had a similar . issue where keys would more visibly just get stuck down. Sent it . in twice; four months later the issue cropped up again. My company decided to just upgrade to the 2018.
The 2016 had a host of issues. Ironically the keyboard was fine, but the battery pretty quickly started failing (there's a recall program for them now, which started a year after mine started showing symptoms and I was t old by a rep that "there's nothing we can do here, we can send it to Cupertino but you'll be without it for about 2 weeks"). The single fan in the machine eventually stopped working.
I know that expecting better service than that is asking a lot, because no one else does much better (except maybe Microsoft, if you have a MS Store nearby their on-site support is far better than Apple's as they're authorized to do device replacements surprisingly often). But that's not what I expect; what I expect is for these things to stop failing so often such that support is necessary. Its not that hard; they had a perfect formula with the 2013-era devices. But they won't admit . that they made a strategic mistake with these new body designs and revert back to something that actually works.
