Airtag Contact Info Registration Issues

Just got my Airtags and there is an issue (resolvable) when you have 2 trusted phone numbers associated with your iCloud account.

Basically during the registration you are asked to confirm the contact details for you iCloud account which are the email and phone number.

If you have 2 trusted phone numbers associated with your iCloud account then this setup process will only ever use the last of these numbers and you can't change it. So if you have a second phone (not your primary contact number) you'll have to remove this from the trusted phone numbers before setup so your primary number is the correct number used.

Once you do this you can register the Airtag with the correct number.

Hope this helps people and if someone knows of a solution I'd be grateful.
