I enabled Google reCaptcha V2 Invisible for the Contact form, but whenever a customer tries to submit a message through the Contact form they get an "Incorrect reCaptcha" error. I also noticed that the usual "protected by Google reCaptcha" badge is not displaying in the Contact form even though I enabled Google reCaptcha for Contact in the admin panel. The site is running on Magento 2.3.2. Anyone experience this error before / know of a solution for this problem?
I was having the same issue and after dubbing I have found that the Google Re-captcha is working if we update contact_index_index.xml so I have remove my modification from contact_index_index.xml and the re-captcha is working fine now.
