I'm using the Contact Form 7 recommended captcha, Really Simple Captcha (no others work) in the Salient theme. The form is responsive but the captcha is not on mobiles. You can't read it, let alone type it into the spam box. I also looked it up and you can't force a change to the image size so this makes the form obsolete. I've tried installing another captcha type, but the form won't read it.
Any help would be so appreciated. Thanks,
