Started getting the CAPTCHA bug / failed sign in loop today (UK based no VPN). Previously just had the standard CAPTCHA not showing up on page load, then having to sign in a second time. Annoying but at least could get in.

Might be something to do with ad / script tracking blockers, as it stopped when I disabled uBlock Origin on Chrome. Haven't properly tested but also had the same issue on a clean install of Firefox which has blocking out of the box.

Would be great if Air NZ could streamline auth, and perhaps move to something like hCaptcha, rather than reCaptcha.
