Yup i also got the same problem. After checking the code i found out that with the field_group.js
It was calling an id that does not exist in the new version of acf.
so i tried removing the id from the jquery selector
$(‘.location-groups td.value select:visible’)
Now the input field for the meta key and value is already being shown but the problem now is that when you try to update. It seems that the meta key and value are not being saved. Another problem is that there seems to be a problem with the js file preventing you from adding more rules.
I hope this gets fixed as well. Need this on one of my project.
Actually, since posting my last comment here I have created a plugin that does this. However, the plugin can slow down your admin and it’s not really a good idea unless you really need it. You can dig through my code and implement it for your specific fields on the site.
Like I said, while I build this I would not use it as it will run JS on every choice field in all field groups one the page and it would be better to target only your specific field. For example, targeting a specific select field would look something like
// replace data-key with your field key
'change [data-key="field_12345678"] select': '_custom_field_location_change_select'
