Hi, as cartagena68 said, you need to click on view more, press it again if it didn't quite catch it first time. Also, when adding, you must click on a blue Add *** button, hitting ENTER on your keyboard will close the popup window, but it will not work, so you have to click Add new button again to bring the window back and click the Add city/region button properly. This should be improved to have ENTER key support.
Regards
