Thanks for the answer but this doesn't really help me much. As I explained, we are not changing devices, clearing cookies, or logging in from a new browse. We are entering the site on one browser, and being fed a different experience every time we click onto a different page that contains the experience (which is all pages because we are running a global navigation campaign). Is there any other reason the PCID could be changing in this situation?
A quick follow up, I've been doing some QA on this and it turns out that any test created in the WYSIWYG editor is reproduced fine, but for this particular test in the form based creator it's randomly showing up when we refresh the page. Would it help if someone could take a look at the code and potentially identify the issue?
Can you please share the URL of your Website as well as Adobe Target Account Login details in a private message so that we can debug the issue at our end.
Waiting for approval on this, will get back to you.
