I have managed package and have major release for this. This release also includes changing the default landing tab. We have changed the tab in app xml as below
<?xml version="1.0" encoding="UTF-8"?> <CustomApplication xmlns="http://soap.sforce.com/2006/04/metadata"> <defaultLandingTab>XYZ</defaultLandingTab>
This works fine with the fresh install of the package but if I upgrade the package from previous to new one the default tab is not changing. Is is this the limitation for managed packages in case of upgrade.
