SessionWizardView compatible with RECAPTCHA (django-recaptcha)?

[Duvodas]

Hello,

I have issues implementing googles RECAPTCHA at the last form of my 3-step SessionWizardView. While testing I always get "ReCAPTCHA validation failed due to: ['timeout-or-duplicate']" in the server log, even if I click through the forms in seconds.
The captcha works with a basic view with only one form, so I assume everything with the configuration at google and with the keys is fine.

Are there known incompabilities using the captcha with the SessionWizardView?

Thanks for help
