Jupyter Notebook Issue

Hi @ZAYEDHEMAID

in the past the workaround seemed to work if the server-side was not the problem:

adding ?forceRefresh=true to the url and opening again

Here you can also find an excellent thread on a related topic and consider e.g. renaming the notebook, which can help before enforcing refreshing as mentioned above: How to Get a Clean Copy of an Assignment Notebook

Please let us know if this helps!

Best regards
