Lots of individual / hobbyist developers are no longer publishing to the EU App Store due to Digital Services Act regulation and compliance.
it’s too damn spooky. i know they rolled back or caveated some of the language after the uproar but i certainly would like to travel to the EU without any kind of anxiety about “do my open source apps mean im an EU felon if i forget to check github issues for security issues”
Crimes require criminal intent, generally speaking.
I know startups who don't publish to certain EU countries because they have to fill "a big scary form"
You can always switch to US app store region (cancel exisiting subscriptions, leave family, and wait until apple music/tv subscription is expired).
You won’t be able to use non-US credit card for the app store but you can always buy US virtual apple gift cards on amazon straight from apple shop there.
I guess it’s easier to find a testflight link if one is set up, or just to create a new account altogether, and sign in to it temporarily.
