Jupyter Notebook doesn't exist anymore

[Simranjit]

I had made a notebook and bookmarked it, but now am just getting redirected to this page. My notebook also doesn’t exists in the JupyterLite files

There is likely no way to retrieve the notebook. A JupyterLite site such as try.jupyter stores content in the browser’s IndexedDB, which persists only as long as the browser’s storage is not cleared, or the underlying version changes significantly.

Individual new/changed files can be downloaded from the file browser (either on the separate page for the /notebook/ app, or the file list in /lab/) and then re-uploaded.
