Add City button missing

The eight regions of Slovakia are as followed:

Banskobystrický kraj Bratislavský kraj Košický Nitriansky Prešovský Trenčiansky Trnavský Žilinský

Thanks for your message.

I added those regions and you should now be able to add cities after navigating into the region. You should see the "Add City" button on the top right corner.

Thank you!
