Do I need to resubmit my app to the App Store if all I want to do is add an additional country to make it available in? Or can I just add the country on the Pricing and Availability page and save the update to make it available right then?
Resubmit app after adding new country?
No, you don't need to resubmit. You just have to check you comply with regulation such as for encryption.
Thanks for the reply. So to be sure...in my case, my app is available only in the US, but I want to make my app available in AUstralia. So if I select the checkbox for AU and hit save, it's now available in the AU app store?
For future references, the App Store Connect Help resource has a lot of information about how to use App Store Connect.
