Apple account blocked when using Sign in with Apple on Chrome

When using Sign in with Apple on Chrome our Apple accounts are becoming locked. After unlocking we are unable to sign in to our website using Sign in with Apple - possibly due to the 24 hour waiting period. Safari works fine.

Prior to today this worked perfectly. Something changed today either with Apple, Chrome or Firebase.

Any ideas on how to resolve this issue would be great 🙌🏾
