Angular Universal build always adds the app.component tags about universal HOT 4 CLOSED

updateTag() isn't the default behavior?

Because because you are explicitly using the addTags API. Having multiple meta tags with the same name is valid HTML.

Example:

<meta name="robots" content="noindex">
<meta name="robots" content="nofollow">

Will be aggregated as

<meta name="robots" content="noindex, nofollow">

See: https://developers.google.com/search/blog/2007/03/using-robots-meta-tag

In your case, you should use updateTags which under the hood will call addTags when the tag does not exist in the DOM.

This is expected.

@alan-agius4 Could you explain/give an an example why the updateTag() isn't the default behavior? Why would I want to keep multiple meta tags from different pages?
