Per Language Codes | Crowdin Developer Portal, the language code for Chinese (Simplified) is zh-CN. When I add the language to my project and force sync with my Github project, CrowdIn fails to find and pick up my zh-CN translated files. Instead, it creates a pull request to add empty resx files for language code zh?
We’ve figured it out. CrowdIn was configured to emit a two digit language code rather than the complete language code.
@Tkael Crowdin supports different configuration, like 2 characters code, 3 characters code, and different locale patters zh_CN, zh-CN, probably with custom language mapping should be possible to add even zhCNcn in case you wish so
