The analytics calls that are captured for one user are not the same as for the other user. So if I load a page I see the image request fire for one user and the other user may not see it. We clear browsers and follow the same clean up protocols but the results are very user driven. So our Unit testing team may see one result, QA sees another and the UAT team may see one or the other. On checking with Adobe they suggested an option in Chrome based browsers to bypass service workers for network requests.
This workaround will only function as long as the dev tools drawer remains open, hence looking for other solutions, if any.
