xamarin.android - After updating xamarin forms, stacklayouts inside relativelayouts are not laying out properly -

some of stacklayouts wrapping content width/height rather using constraints given them when adding them relativelayout. example of happening navigation bar. create this

var leftbuttonlayout = new stacklayout {   children = { _scenemaintoolsview.menubutton, _scenetitle },   orientation = stackorientation.horizontal,   backgroundcolor = color.fromhex(colours.orange),   horizontaloptions = layoutoptions.startandexpand,   spacing = 8 }; 

i add relative layout

_layout.children.add(leftbuttonlayout,   constraint.relativetoparent(p => 0),   constraint.relativetoparent(p => 0),   constraint.relativetoparent(p => p.width),   constraint.relativetoparent(p => navbarheight)); 

and later set contentview's content property

content = _layout; 

this has been happening since updated xamarin forms nuget package 2.3.0.49 (necessary use dll's). know why happening or how fix it? i'm testing on android 4.4.2 (kitkat) , compiling using 6.0 (marshmallow).
