What breaks visitor tracking on Bubble.io?
Scripts in HTML elements only execute in run-mode (published), not in the editor canvas preview.

Then run through the labeled QA checklist before you rely on the numbers, and set expectations with the match-rate calculator — no vendor identifies every visitor.
