If you have shared the link of your notebook which you found on the top of your browser, and the person complained about this.
So, now lets get on to fixing this problem. When you make a new notebook you will reach this page.
Then if you click on the file button on the top left corner. A drop-down menu will open up.
Click on the share button which is available in the menu. Doing this will open a internal tab allowing you to either share the notebook with a few peoples by keeping it private and searching them by there username. or make it public so that everyone can see.
Thank you.
