iPhone 15 not sharing location

So, I tried a bunch of different things.

Settings > Mobile Data and then Enable for Find My

didn't work for me, even after reset,

HOWEVER—in Settings > Find My, there was an option to opt-in into something called the Find My Network.

I did that + resetting my phone and Find My location is working normally again.

I am using the Find My iPhone to share location with people and now one of those people cannot see my location and I am unable to share my location with them

I have reset my phone. I’ve restarted my phone. I’ve turned things off. I’ve reset it checked every possible thing and I still receive a message that says

“share location unavailable. Please try again later.”

it only started since I’ve had the new iPhone 15PRO No issues with my previous iPhone 11. I Have researched every possible thing to do to make this fix. Can I return my iPhone 15PRO and get one that’s functions as it’s supposed to ?
