Here are a few key things to know about native regions:
Account settings apply everywhere. If you set a native region at the account level, every project (new or old) will use that region by default.
Project settings override account settings. If you change the native region inside a specific project, that project will use its own setting—even if your account has a different default.
Chose Where to Set Your Native Region:
If you work exclusively in one area: Set it at the account level.
(Set it and forget it.)If you work in many regions: Skip the account setting and set the native region in the project settings.
If you share an account with others: Unless everyone designs in the same region, set it per project and skip the account setting.
