I tested it with my phone and got similar results: I got only 9 out of the 21 QR codes to work. I don't know why you think such a finding should not be mentioned here.
I think it should be mentioned but without the "so I'd recommend against using", because that's wrong. Also, specify OS, surface, time, etc for better test!
> "so I'd recommend against using", because that's wrong.
Someone's opinion is not "wrong". It may be misinformed, it may be different than yours, but you can't just assign a "correctness" value to something subjective just because you disagree with it.
No, that's not it, but I get why you read it like that. By "wrong" I mean the lifting his personal test/opinion to the level of a general "recommendation", in effect discouraging others from exploring, and harming the creator. That is one wrong here. You get it?
