Yes this has been happening to me too @flowgurus - highly annoying. I have noticed this for several weeks. Usually logging out and logging in has fixed the bug, but not today. Any help is appreciated Webflow.
Thank you for sharing the site. This issue hasn’t been fixed yet. Sorry for the inconvenience and thanks for you patience. Will give an update when possible.
Hey @flowgurus, @drew-eastmead and anyone else monitoring this issue, the issue was identified and a fix has been been pushed to the Designer. Hopefully this fixes it for you, but let us know if you continue to experience any problems with copy/paste.
