Target works fine on Case 2 but not 1. For #1 i see console error
[page-init] Adobe Target content delivery is disabled. Ensure that you can save cookies to your current domain, there is no "mboxDisable" cookie and there is no "mboxDisable" parameter in query string.
I am having the same issue while I found that Target(mbox) cookies are not getting successfully stored on my site while I am not pretty sure what to do to have it stored. Would you mind share a bit more of it?
