Hi Ged 

Thanks for reaching out in the Lucidchart Community! We have recently made changes to the Lucidchart’s documents page which may be causing this confusion. You should be able to find your “Shared with me” section as a subsection under “Documents”. If you have many folders on your “My Documents” you may need to collapse that section so that you can see your “Shared with me” items. You can do that by clicking on the small arrow right next to “My Documents.” 

If that’s not the case could you please provide a screenshot of the issue so I can take a closer look? Thanks!
