Hi everyone,
Thanks for your patience while we checked this with the team. I wanted to share a quick update here. As of now, InCopy on the web (Share for text editing - beta) is supported only in Google Chrome. Other browsers, including Microsoft Edge, aren't supported at this time, which is why you're seeing the 'Incompatible Browser' message when opening the link in Edge.
The help documentation has been updated to reflect this clearly, and you can refer to it here for the latest supported browser details:

For the moment, please open the share link in Google Chrome to access and edit the document.
I appreciate everyone flagging this and sharing your observations.
