One thing I can't find an answer on is, how does it work with shared items. For example, we have a set of keys for things around the house (i.e., the back door, the shed, etc). They aren't one person's item.
I have family sharing turned on, so all of the apple devices everyone in the family owns show up in the Find My app. Will the tags work the same way? In other words, if I register the tag attached to the back door keys, will my other family members be able to locate them with their iPhones? Or will they have to ask me to do it?
