App Attest counter value reset to 0

Hi,

I am new to iOS development and currently studying App Attest functionality. Can someone confirm why the counter value be 0 during attestation validation at the server side.

And also, can this value be reset to 0 at any point of time?

Do we need to do code signoff as well for using App Attest?

It should never reset to zero.
