I have the same issue in IE 11, windows 10, Esri JS SDK 4.3
I've tried every possible <meta tag stuff I could find on the interweb. What is weird is our 3.x version works great. The same <meta tag from our 3.x version still has the 4.3 version not work. My guess is that the map never even sees the pinch and the browser does its normal sizing thing. There must be a way to shut that off.
Things I've tried:
<meta name=”viewport” content=”width=device-width” />
<meta name="viewport" content="initial-scale=1, maximum-scale=1,user-scalable=no" />
<meta name="viewport" content="target-densitydpi=device-dpi, initial-scale=1.0, user-scalable=no" />
<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1, user-scalable=0"/>
<meta content='width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=0' name='viewport' />
<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=no" />
<meta name="viewport" content="width=device-width, user-scalable=no, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0">
Any thoughts would be most appreciated.
