Background of the issue:
I have successfully created two custom Chinese languages for my site hidden link using WPML. One is for Chinese Traditional with the language name 'Chinese (TC)', custom code 'zh', default locale 'zh_HK', hreflang 'zh', and language mapping 'Chinese (Traditional)'. The other is for Chinese Simplified with the language name 'Chinese (SC)', custom code 'zh-cn', default locale 'zh_CN', hreflang 'zh-cn', and language mapping 'Chinese (Simplified)'.
Symptoms:
When I try to switch from the main menu (ENG) to the custom language in Chinese (TC) or Chinese (SC), there is no page available. I also tried to create a menu in both Chinese (TC) and (SC), but there was no translated page for either of them.
Questions:
Why are there no pages available when switching to the custom Chinese languages?
How can I create translated pages for the custom Chinese languages?
