The current autocomplete API is useful; however, if we implement custom logic exclusively for one country, autocomplete becomes disabled for all other countries. This could lead to a less ideal purchasing experience for stores that operate globally.
It would be highly beneficial if apps could override Shopify’s standard autocomplete so that a custom logic can be applied only to a specific country (in our case, Japan) while maintaining the default autocomplete for every other region. This approach would ensure a better user experience for international merchants.
