Background of the issue:
We are currently using the directory name "zh-hans" for our Simplified Chinese pages, as recommended by WPML. Our current hreflang implementation looks like this:
Symptoms:
A recent check flagged "zh-hans" with the issue "Unknown country code".
Questions:
Is "zh-hans" the correct directory name and hreflang value for Simplified Chinese content?
Are there any potential SEO implications we should be aware of with this implementation?
If there's a more optimal approach, what would you recommend?
