save() operation returns the updated user object that you can use in your app. However the
currentUser() is not updated by this operation, but it should update the next time you refresh the jwt using
.jwt() (https://github.com/netlify/gotrue-js#get-a-jwt-token). Note that if your current JWT isn’t expired then you have to pass a truthy value into the
jwt() call to force it get you a new token. Or you can log out then log back in again. Let me know if this helps!
