I have a Managed Package, including a custom Lead page layout, which was released a while ago. I made a change to the layout and uploaded a new package version (Beta 1). I see in the package description as well when I install the package that the new layout is not being taken into the new version.
Anyone knows why and what I need to do for this to work?
As per the SFDC ISV packaging guide you cannot update the page layouts .The page layouts are not up-gradable and hence only way you can launch new layout is create another page layout and probably deprecate the older one .
