find my in the same account
I just bought a new iPhone and my old iPhone is still working. These two phones use the same apple account. But I couldn’t find a way to share the location between these two devices.
Question marked as
If you open Find My app on your iPhone, tap Devices at the bottom, and select the iPhone of interest, does that work for your needs?
If you're looking to provide others with your location, you select which device(s) you want to use for that. Select "me" at the bottom of Find My display, and select which device(s) you want to use to report your location to others.
