Precision Find Friends Not Working

My wife and I both have IPhone 15 Pro Max. We have both shared and followed each others locations. When we open the Find My app we can get GPS directions to the others’ location but the box for precision finding the other is always grayed out. It says that the other’s account or device is not compatible with this feature.

This is a big bummer because I would love to use it to find my wife more easily in the grocery store. I have tried many suggestions online such as restarting the phone, stop following each other and reading, making sure that the correct Apple ID email address is stored in the contact card, restarting location services, checking permissions, etc. I have done this on both phones and still can’t get the precision find friends to work. I hope someone can help here.
