Re: it will not let him share his Apple News subscription because it says we are in different countries
Wondering where that is showing up:
Eg: maybe one of you may have changed their region code in the App Store.
Eg: See how you can: Change your country or region code in the App Store on Mac - Apple Support
or
You could check your online Apple ID accounts are in order (or edit any out-of-date details)
Apple ID log-in: https://appleid.apple.com/
If needed: Apple ID support website (info / support / contact options etc.): Apple ID - Official Apple Support
or
Billing and Subscriptions Support website: Subscriptions and Billing - Official Apple Support
All the best :-)
