Hi,My app is already published but I need to change the primary language from English to Polish.Unfortunately Polish is not an option in the dropdown menu on iTunesConnect.On the internet I read that I have to add the new language in xCode and then upload the new build to iTunesConnect.I searched for a long time now but I cant find a good instruction on how to do this properly and I guess I cant test it before it will be accepted by the review team.Could you please explain me how to change the language in iTunesConnect from English to Polish for the app?What I did so far:In xCode project settings under "info" I added the key "Localizations" and to this key I added the value "Polish".Polish was here again not available in the dropdown menu so I had to write it myself. Here is the problem: Which format should I use? (Polish, pl, Polski?)Now I have English and Polish as values for the key "Localizations". (My goal is to display in the store only Polish for this app)Thanks a lotBest regardsFabian
