<p>Some countries require that websites notify customers about the use of cookies. Previously you could do that under <b>Settings → Security</b>. That setting has now been moved to the <b>GDPR Compliance (EU)</b> add-on. Here's what we advise doing:</p><ol><li>Go to <b>Add-ons → Manage add-ons</b>.</li><li>Switch to the <b>Browse all available add-ons</b> tab.</li><li>Make sure that the <b>GDPR Compliance (EU)</b> add-on is installed and active.</li><li>Click on the add-on name to open the its settings.</li><li>If the <b>Cookie consent</b> setting is set to <i>Implicit</i>, then your store behaves as before the upgrade.</li><li>Switch to the GDPR tab and make sure that the notifications about personal data processing are configured as you want them to.</li><li>Click <b>Save</b>.</li></ol><p>If you'd like, you can set the consent mode to <i>Explicit</i>; that way customers will need to explicitly agree to the use of cookies before they can access your store.</p>
