Hey, thanks for the report. This is a known bug in the review system state management that the team is already tracking.

To help prioritize a fix, could you please share:

• Console errors: Help → Toggle Developer Tools → Console (a screenshot of any errors)
• File type: does this happen only with your .cpp file, or with other file types too?
• Request ID: Chat (top-right menu) → Copy Request ID

Temporary workaround: use Git to review the actual changes instead of the in-editor review system. The code changes should still be applied correctly even if the UI buttons don’t work.

Let me know if the file changes are being saved despite the UI issue!

Thanks for your help.

1. 
2. Only happen on a certain cpp file. Others work well.

The file can be correctly save,this bug doesn’t block my workflow, just confusing.
