Hey, with the changes to Chat and Composer now being unified into one panel, this does mean than in certain later releases, users may face connection issues if within a high-security network that doesnt support HTTP/2.
The good news is we have a fix that we are testing internally, but should allow all Cursor features to work, even inside networks where HTTP/2 is not supported!
We are finalising the update at the moment, but I would expect this to be available within the next 48 hours (hopefully sooner!)
