Is there anything additional which needs to occur with the latest fix for recaptcha on forms?
On this site here (Book a reading form - note - payment gateway is in test mode, so good to test) https://akashic-studies-australia.prod01.sydney.platformos.com/akashic-readings
I am getting a recaptcha error

Nope! The recaptcha is set to 1.0 for that form so it will be incredibly stringent on what it lets through/rejects
I just tested and received a 0.9 (see below) and so I correctly got rejected
