I will release my iOS app soon and I read that there is a delay for up to 5 hours until the app is available on the AppStore worldwide. I'm in Austria (Europe), how can I check if the app is already available on the US AppStore? (or better yet if it's available everywhere)
I only know of a manual way checking it.
Open App Store and click at the flag circle bottom right.
Now select the country you want to check for your app.
