Parcel list is loading slowly

Hi,

the plugin is very interesting and has many great options, but the list of parcels / terminals is loading very slow (3-4 sec).

I set the plugin to show only parcels in the city typed in checkout form, but it didn’t helped. Also i deactivated all plugins and switched to twentytwentyfive theme – with no results. Is it any possibility to get list of terminals (InPost) faster?

My hosting is fast and website is not working slowly.

Regards,

Szymon
