Hi there SausalitoDog,
Thanks for using the Apple Support Communities. I understand you’re having issues sharing your Apple News+ subscription. I’ll be happy to help with this.
If you're using Family Sharing and someone in your family group subscribes, you should see a message that you have access to the subscription when you open the News app and everyone in your family group should automatically have access to Apple News+ after you subscribe:
Join Apple News+ in the News app
If that’s not working as expected, start by restarting the iPhone that is having the issue and try accessing an Apple News+ article once more:
Restart your iPhone, iPad, or iPod touch
If that doesn’t work, check for an update in Settings > General > Software Update. If you do see an update available, back up the iPhone and install the update with these steps:
Update your iPhone, iPad, or iPod touch
If the issue continues after that, go to Settings > Your Name and tap Sign Out. Restart your iPhone once more and sign back in. See if you can access the service as expected then.
Best wishes.
