How is the instance language selected ?Issue The instance UI language is decided according to the following criteria: - If the user has a language user preference, the system will use this preference for the UI language. This preference can be set in the system settings language drop-down box. Setting a language preference will create a record in the sys_user_preference table with the below details: name = user.language value = ISO 639-1 Code of the selected languageuser = actual user - If no user preference is found, the system will look at the language column in the sys_user table. If set, the system will use this language for the UI.- If no user preference is found and no profile language is set, the system will use the language set by the system property glide.sys.language.
