Siri requires iPhone unlock for shared reminders after iOS 27 update

Siri AI can't add things to a shared reminder like a grocery list without unlocking the phone.

This was a very frequently used feature by my wife and I when adding shopping items and groceries, while the phone was on the counter or in our pockets and we had earpods on. But now, after the iOS 27 update, Siri asks to unlock the phone every time.

It adds to other reminders just find without unlocking.

I'm assuming this has something to do with the reminder being a shared artifact?

There has to be a fix for this. Or something in the setting that I'm not seeing.

Using: iPhone 15 Pro and iPhone 15 Pro Max

iOS 27 on both phones

Siri AI on one and no Siri AI on the other.

The phone without Siri AI does this just fine without issues, but it's Siri AI that's having issues.
