HTML/Href lang mismatch

Using WebFlow’s built-in functionality to provide a site in NL/EN.

Ran a crawl, and seeing an hreflang and HTML lang mismatch.

It seems that the following "lang=“nl” is being embedded on English pages, meaning this should be lang=“en” not “nl”

This is being auto-added by WebFlow.

Any way to correct this?

Check your site-level settings in the dashboard, and make certain you do not also have a language specified there. This will conflict with the new Localization feature.
