Check Settings > Privacy & Security > Location Services > Share My Location.

The only way is that you either need to add the second email service provider, which is an iCloud email address that allows you to share the location across the devices,

OR

sign out from Apple ID and re-sign in with an iCloud email address that also allows you to share the location across the devices if your partner has the iCloud email address.

keep in mind if another email service providers than iCloud might not be working to share the location across the devices

Perhaps your iPhone is damaged. Let Apple assess it.

iPhone Repair & Service - Apple Support

My husbands location won’t show to any one and says the same thing. I called Apple support their techs worked with me for over 8 hours and nothing worked. The weird thing is I put Life360 on it and that works. I’m wondering if any of it could be from the watch and it Shay’s share my location from this phone and iwatch.

Apple had us completely reset his iPhone to like new out of the box and it still didn’t fix it they never once offered to bring it in anywhere. I took it too AT&T where we got the phones and they were useless as well

My son's phone can no longer share his phone's location with me - gives us the same error. But sharing works with my wife and others, so it's not privacy settings. Definitely a new apple bug that will never be fixed.

Same here. Started late October 2023. Says “Share Location

Unavailable. Please try again later.”

I tried updating iOS, restart, and every setting I could find. No luck yet.

Did anyone get a fix for this?

We have a family of 5 and "share my location" works for all but one of us - settings are the same across devices.

Appreciate all suggestions
