reality really stands over fiction
This story about a magic cloth purchased as a joke is astounding.
I’m sorry about this incident with your device, but prefer to see the good side of things: solution seems granted for you. Nice.
(I live in the farthest place from any Apple Store in my country, my 16” arrived today, everything perfect so far…)
After reading your post, I’ve carefully checked the screen coating, which is an important and delicate “part”, as you say. I believe it is delicate, but mostly regarding the manufacture finishing. It should be similar to iPads & iPhones coating, designed to touch.
After all, I’m prone to think you’ve been lucky: better to find a problem in time to exchange the device
