not assessable is recorded when the rule applied but the store could not be judged on it (bot protection, a region lock, a step we could not reach), and not applicable when the store has nothing for the rule to judge. Those stores are left out of every number on this page, never guessed. Why we do that
Why it matters

The card-payment form is missing the `autocomplete` attributes mobile browsers need to autofill saved cards.

iOS and Android can autofill a saved card in one tap when the fields are labeled correctly. Without it, the buyer types 16 digits, expiry, and CVV manually, and many abandon.

That sentence is the one a failing store sees in its own UXFix report.How rules are weighted and scored →

The fix

The same steps a failing store sees in its report

A pass means: All card fields have correct autocomplete.

Severity
Medium
Score gain
+1.0pts
Page
Checkout

Score gain is roughly what a fail-to-pass change adds; rules that could not be judged are left out, which can move it a little. Re-run a free audit after the change ships to confirm the verdict moved.

Checklist for the pass
0 of 3

Tick each step as you ship it. The audit judges the live store, so re-run it once all of them are done.

What our auditors say about this rule

The phone can fill in the card from the wallet or the camera, but only if the form lets it.
