There was a bug that FindMy wasnt working at all for people that you are sharing your location with. In this beta it has been fix. My location as well as others that I share with are populating just fine.I’m curious what your specific bug is? I’ve had an issue for months now where Find My just fully removes my location exception, which happens to be home.
So every day when I leave I get alerts about leaving items behind that I don’t want that alert for. Unfortunately this has persisted from iOS 17 into 18 PB4.
I was really hoping for a fix.
I have not had the bug you mentioned.
