Can't Activate Subscription – CVV is Required

I had the same issue. Then I went to https://wp-stream.com/pricing/ in an incognito window, logged in with my wp.com credentials and was able to register a site. Maybe try that for now?

@nelsonjoyce thank you, that actually worked! A little irritating that I have to do that, but it’s better than nothing. Thanks, again!

Did not work for me. Unable to register a site using IE, Firefox, or Chrome incognito window or not ??

Same thing here, I first noticed the issue around 24 hours ago

Samething here, for all my sites (5)

This issue has been resolved.
