It’s a very confusing and hidden feature. You have to start “deleting” your phone from Find My (which is itself an hidden swipe action) and it’ll tell you that you can’t but you can enable repair mode.

IMO the feature shouldn’t even be in Find My because it’s not really related to finding your phone or activation locking/unlocking it.

I'll take shipping the org chart for a thousand Alex.

2016 is before repair mode existed

Oh I meant it should not be a discovery issue if this is the standard procedure. The user don't have to know the feature exists.
