Apparently works only until Woocommerce 8.3.1

I second that, I have the same issue. If the plugin is already configured it works.

Regarding the lack of similar plugins I’m kinda worried.

Yupp, same issue here….

in the file
/woocommerce/assets/js/admin/wc-shipping-zone-methods.min.js

there is a function
moveHTMLHelpTips: function(n)

this switch can be commented out:
if (o.some(e=>a.includes(e))) {
t.find(label[for=${a}] span.woocommerce-help-tip).addClass(“wc-shipping-visible-help-text”)
} else {
…
}

and the front-end form works again

not ideal because it is editing the woocommerce core js file but it gets it back working in the meantime

the if part can be commented out, the else part is needed

Thanks for the report. I am fixing this.

Still not working! The plugin is useless without the interface.

Any news on a resolution for this issue?

Fixed in version 2.2.0
