Find My redirects to Amita when entering a phone number

Find My redirects a phone number to “Amita” because that number is saved in the device’s contacts (or in a linked contacts account) under the name Amita. Find My always matches against contacts first. Remove or edit the Amita contact (or disable linked contact accounts), and it will stop redirecting.

Find My only allows location sharing with Apple IDs, not just raw phone numbers.

So if the person does not use iMessage (green bubbles), it can’t share anyway.
