This thread is resolved. Here is a description of the problem and solution.
Problem:
The client needed to ensure that hreflang tags were added to each URL in their sitemap for all three languages, as Google was not recognizing them. They were using the All in One SEO Plugin to generate the sitemap.
Solution:
We informed the client that WPML automatically adds hreflang tags to every page of the site, which should resolve the issue with Google not recognizing all languages. We reassured the client that there was no need to manually add hreflang tags and provided a screenshot to show that the hreflang tags were indeed present in the page code.
If this solution does not apply to your case, or if it seems outdated, we recommend opening a new support ticket. We also highly recommend checking the related known issues, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins.
