What is true for environments where JavaScript tags are not allowed or supported?

When JavaScript tags are not allowed or supported, Tag Managers cannot function as intended. These systems rely on JavaScript to inject tracking codes and collect data from web pages. Without the ability to execute JavaScript, the Tag Manager is prevented from automatically collecting data, as its core mechanism for interaction with the webpage is disabled. This means manual data collection or alternative, non-JavaScript-based tracking methods would be necessary. The Tag Manager does have limitations, and its ability to automatically collect data is directly tied to JavaScript support.
