Hey, thanks for the report. This is a known issue. The same bug showed up for several users after updating to 2.3.34: Agent instantly reports "no changes to review" with Find Issues
The team is working on a fix. It happens most often when the workspace root isn’t a git repo and the git repos are in subdirectories, which matches your setup.
Temporary workaround: try opening the specific subdirectory that contains the git repo directly in Cursor instead of the top-level workspace. In those cases, Agent Review usually works.
I’m tracking this issue for the team.
