# Missing \`update\` signal #### Description The `update` signal in Google Consent Mode is **not being sent**. This signal is required to communicate the user’s **final consent decision** (accept, reject, or customize). Without it, Google assumes no decision was made and may disable features by default. #### Possible causes * The script that calls `gtag('consent', 'update', {...})`: * is **loaded too late** in the page; * is **using the `defer` attribute**, which delays execution; * is **altered or cached** by an optimization system such as **Rocket Loader** (Cloudflare), a CDN, or a performance plugin. * The script is **loaded after Google Tag Manager**, which may prevent the signal from reaching Google tags in time. #### What to check **Recommended checks:** * Ensure that the script containing `gtag('consent', 'update', {...})` is: * **loaded without `defer` or `async` attributes**; * **placed at the top of the ``**, **before any other script**, especially **before the Google Tag Manager container**; * **not altered or delayed** by optimization tools (CDNs, Rocket Loader, etc.).
* Use browser developer tools or Google Tag Assistant to confirm that the `update` signal is correctly triggered.
