This must be question of generations. From old community posts back in 2016, until now, I see now changes or actions from Shopify.
Maybe these Asian countries are too small to make a different.
Is there so much to ask to shrink down 2 irrelevant name fields into 1?
But Shopify decided to make it even worst, they make First name optional. This would create a big mess in terms of keeping things organized and third party integration - especially email marketing which we only use first name (in Asia).
Other solutions like having an app to pre-collect info would be not useful as well.
