I am having the same issue as everyone else. Works in Edit mode, but does not in live.
I tried the workaround suggested on the last post, making a change and then choosing Save, instead of Done, and it still does not work.
I tried numerous ways of editing. Just adding an extra character to the page. I changed a setting with my newsletter. Then even disabled reCAPTCHA, saved it, then enabled it, and saved it again. Still works in edit mode, but does not in live mode. Also made sure that I was using V2.
