SKExternalLinkAccount not choosing the right URL for phone region

Hello!

I am working on a reader app that supports 4 languages: Danish, Finnish, Norwegian, and Sweeden. The content's language is either the phone's preferred language, if it is one of the 4, or is chosen by the user on the first app start.

As per Apple's guideline, I implemented the ExternalLinkAccount flow, and for localizing the URL I added SKExternalLinkAccount into the Info.plist file. For debug purposes, the default URL is google.com. This is how it looks:

	<dict>
		<key>dk</key>
		<string>https://historienet.dk/abonnement</string>
		<key>fi</key>
		<string>https://historianet.fi/tilaa</string>
		<key>no</key>
		<string>https://historienet.no/abonner</string>
		<key>se</key>
		<string>https://varldenshistoria.se/prenumera</string>
		<key>*</key>
		<string>https://google.com</string>
	</dict>

I have a question and a problem:

1. The problem is that on iOS 16+, the URL opened after pressing the Continue button on the ExternalLinkAccount sheet is always the default one, regardless of the app's and phone's language and region. On what does it rely to display the localized/regional version of the URL?

For debugging it, I tried obtaining the Norway or Sweedan URL on the simulator by changing the app's language and region from the scheme, the simulator's language and region from Settings, and tested it on a real device with the region and language changed to Norway/Finland using a TesFlight build. I had no success.

1. Can I control/influence which region is selected?

Because the user can select a language for the app content, it would be ideal to reflect it on the URL opened by the ExternalLinkAccount flow.
