A limited or premium account is always configured for a language region.
As an account holder of a limited or premium account, you must purchase an additional user license to be able to access the content in other languages.
If you want to use the same account for both languages, contact support after ordering and inform us that you want to assign the license to your existing user.
The license fee for the user is for the language itself, regardless of whether you choose your own user.
The order must be placed through the account holder.
