Details from the Jupyter Notebook Viewer FAQ:
The Notebook Viewer does not store any notebooks. You have to find the original place where the notebook is hosted to update/remove it. Updates occur automatically, but can take some time to appear, as we cache rendered notebooks for approximately 10 minutes. To force an update, append
?flush_cache=trueto the viewer URL.
