After someone clicks “Reject all,” what do you check to verify their choice was respected?

Here’s a test I’d run in MANTIS. I’d start with two fresh browser sessions, record the same page in each, and click Reject all in one and Accept all in the other. Then I’d repeat the same action, like opening a product page, and Compare the captures.

If a GA4 request appeared after Reject all, I’d open it in the request tree and check three things: what triggered it, what data it sent, and what consent state MANTIS observed when it fired. I’d also check whether the browser stored or sent an analytics cookie. The request alone wouldn’t tell me whether the choice was respected. The payload, cookies, and timing would give me a clearer picture.

What’s the first thing you check after “Reject all”? What would make you dig deeper?
