As Post Install Scripts are too limited for my purpose I added a custom Config page to my Managed Package because it displays nicely after the installation is done.
The problem is that the installation now is taking longer and switches into this asynchronous mode where the user is told that he is going to be notified by email when the installation is done.
In such cases, no Config page is shown. I know that the user can load it via Setup > Installed Packages but that's not the same.
So my question is:
- Why do some installations run instant and display the Config pages as part of the installations and others don't?
- Is there anything I can do to guarantee that it will be displayed?
