i am using Cloud BC (W1 version)
how do I add available language?
currently i am using English - US language (because only US is available), but we need English - AU Language.
how do i add this language?
If you use the Microsoft cloud version of Business Central then the short answer is that you cannot. It is tied directly to your Azure AD country.
In the order to get the Australian English language (and localization), then you need to start with Azure AD in that country.
This list shows you which language are available with which country version.
thank you very much for your explanation
