Our integration with google's reCaptcha has worked properly for >1yr and still works properly on Chrome 50, Firefox, Safari, and IE. Unfortunately, users have started running into issues validating the reCaptcha on Chrome 51.
The captcha loads correctly, but when a user clicks to interact with it, they receive the following message in the console: Blocked a frame with origin "
https://www.google.com" from accessing a frame with origin "
https://www.plastiq.com". Protocols, domains, and ports must match.
We've reviewed the change logs for chrome and the most recent reCaptcha developer docs, but no luck. Any ideas why this would now change for users running chrome version 51?
