I flagged this answer and it was declined.
not an answer – 1 hour ago declined - flags should not be used to indicate technical inaccuracies, or an altogether wrong answer
The answer is IMO not an answer to the question, it's an opinion. And it asks a question of the OP in a way that I thought was a bit rude.
That's why I flagged it.
Another issue all together is that he is also wrong. Gmail in desktop mode works just fine on an iPad, that was what earned him an -1 from me.
So When should "not an answer" be used here on Web Apps? If it's not for indicating answers that aren't answers?
