Hello, I'm currently facing some issues with localization for the Safari extension on iOS: Issues with Language Tags: Folder names like pt-BR (Brazilian Portuguese) and pt-PT (European Portuguese) placed in the Resources/_locales/ directory are not displaying the respective languages correctly; instead, the default English is shown. Similarly, using folder names like zh-CN (Simplified Chinese) and zh-TW (Traditional Chinese) also results in default English display instead of the intended Chinese language. Conversely, when changing the folder names to pt (Portuguese general) and zh (Chinese general), the languages display correctly. Could you please provide any recommendations or tips regarding language tag settings and how to ensure they are properly recognized according to RFC 5646? Thanks for your help! Best,
