Restore checkpoint button at chat is not working

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

Restore checkpoint button is not working. Previously clicking the button will give a popup asking you to confirm if you want to restore to this point, the pop up no longer shows and nothing happens after clicking the restore checkpoint button

Steps to Reproduce

Make an random change with agent, and try to restore it back to the point before the change was made

Expected Behavior

Pop up appears to ask you to confirm if you want to restore, agreeing restores the code back to the point of the chat before any action is taken by agent. After agreeing code restores to checkpoint. Now all these doesn’t happen.

Does this stop you from using Cursor

Yes - Cursor is unusable

Hey, you might have checked “Don’t ask again.” When you click the checkpoint button, you should see “Redo checkpoint” at the bottom. If it’s not there, recovery isn’t working and we need to find out why. Could you tell me if checkpoints fail in a new chat or only in your older chats?

Hi I don’t recall doing something like what you showed in screenshot. It failes old and new. I tried installing reinstalling different versions of cursor (the one that installs under pogram and the one that installs under user), tried getting cursor to make random code inserts to test the restore checkpoint function. Hasn’t been working.

Could you record a short video?

Ah, thanks for the video. It looks like checkpoints aren’t working specifically with .ipynb files, but they do work with regular files. I’ll pass this to the team.
