Troubleshooting
The conversion action stays "Unverified".
Check the module is on and the Conversion ID is saved. Open the storefront, accept cookies if a banner shows, and use Google's Tag Assistant (tagassistant.google.com) to check your store's page. No Google Ads tag means the module is off, the Conversion ID was rejected (it must be digits, with or without AW-), or marketing consent was not given.
The tag loads but no purchase conversion arrives. The Purchase label is missing or mistyped. Copy it again from Tag setup in Google Ads; it is case-sensitive and has no spaces. An invalid label is ignored rather than sent.
Purchases are counted twice. Another copy of the Google Ads snippet is installed, usually in Tracking Scripts, Google Tag Manager or a theme. Remove it; this module already sends the purchase.
Ad blockers. Some shoppers block Google's scripts, so a share of conversions is never seen. That is a browser choice and cannot be worked around from the storefront.
Turning it off. Switch the module off. The next page load no longer includes the tag; conversions already recorded stay in Google Ads.
